Abstract

The science of quantum dots has evolved rapidly in recent years. A quantitative and comprehensive examination of the research domain is required to identify research trends and directions in the field. This work, a systematic review of 4176 scientific articles published in the Web of Science database between 2014 and 2023, results from collaborative efforts. The results, based on two citation analysis methods- bibliographic coupling and cited reference method- identify some of the most active and influential documents, authors, countries, cited references, and keywords in the field. The study reveals rankings, collaboration networks, and clusters of contributions to the literature. The study found that the most bibliographic coupling documents were Lim, 2015, and the countries with the most publications and collaborations have been China and the USA. Specifically, the fourth cluster of authors is linked with each cluster, and the most frequently cited reference is Murray CB, 1993, Journal of the American Chemical Society VII5, P8706. Quantum dots stand out prominently, ranking second in occurrences with 1864 mentions and relative influence. This research is a testament to the collaborative nature of scientific inquiry in understanding the current state and future directions of quantum dots research.

1. Introduction

Quantum dots, a subject of intense interdisciplinary research in the 21st century, offer unique advantages over traditional fluorescent dyes. The term ‘quantum dots’ (QDs) was first introduced in a glass matrix in 1981

[1]

. In 1985, Brus at Bell Labs discovered QDs in colloidal materials

[2]

. Reed et al. (1988) coined the term “quantum dot” to describe zero-dimensional nanosemiconductor materials. This technology enables engineers to create numerous nanometer-sized building blocks for faster, smaller computer circuits or more efficient light-emitting devices. Recent advances in quantum dots (QDs) have shown that these nanometer-sized semiconductor particles can be covalently linked with biorecognition molecules such as peptides, antibodies, nucleic acids, or small-molecule ligands for use as biological labels. Bailey, Smith and Nie (2004)

[3]

discussed recent advances in quantum dots (QDs), noting that these nanometer-sized semiconductor particles can be covalently linked with biorecognition molecules such as peptides, antibodies, nucleic acids, or small-molecule ligands for use as biological labels. Furthermore, QDs are the composition and dimension of the nanostructure of emission light

[4]

Colloidal luminescent semiconductor nanocrystals, also known as quantum dots (QDs), have received a lot of attention in recent decades because of their unique advantages over traditional fluorescent dyes, such as size-tunable emission, broad photoexcitation combined with narrow photoemission, strong fluorescence, and high photobleaching resistance

[5]

.In addition, QDs are being used to detect physical variables, notably radiation, electromagnetic quantities, temperature, and chemical compounds

[6]

. QDs are well-known for their wide excitation range and ability to emit small, symmetrical peaks

[7,

8].

Recently, QDs have been used as effective tracers for cancer diagnosis and therapy

[9]

as well as QDs are widely used to develop various biosensors due to their excellent optical properties, photostability, favourable biocompatibility and promise for many biological applications

[10]

. Moreover, QDs can be used for brain-targeted drug delivery and to visualize brain structures and mechanisms

[11]

. Researchers have recently focused on exploring QDs toxicity, toxic mechanisms, and biosafety in clinical applications. Many studies have found that QDs can cause DNA damage, elevated reactive oxygen species (ROS) levels, and decreased cell viability

[12,

13]. Also, recent literature reveals that quantum effect particles smaller than 100 nm exhibit atom-like behaviour

[14]

. In addition, Coccia (2022)

[15]

examined the technological trajectory of growth in quantum computing to design a quantum ecosystem for industrial change. Jiang and Chen (2021)

[16]

found that quantum technologies bring transformative changes to our society and ecosystem, synergizing social, scientific, and technological activities. Quantum computation has become an eye-catching subfield in recent years due to its high and intensive knowledge engagements. However, few researchers have systematically analyzed the evolution of scientific output in this domain.

In addition to many scientometric and bibliometric publications and extensive quantum dots research, universities, institutions, scientists, and countries define science policies by analyzing scientific research to address global innovation needs. Hence, developing an outlook for the future quantum market, policies, and semiconductor industries involves identifying key research areas in the field of quantum dots. Gupta, et al. (2021)

[17]

studied quantum dots research in India from 2000 to 2019 and observed significant growth. India published 4,946 publications, with an average of 247.3 publications per year. India registered a 22.46% growth compared to 8.86% worldwide. China and the USA hold the first and second positions globally, with 23.46% and 22.13% growth, respectively, securing India in the third position. Wei et al. (2022)

[18]

conducted a critical study using bibliometric analysis of the Science Citation Index Expanded database from 2000 to 2021. Over the past two decades, there have been 1,557 publications in the field of quantum dots-sensitized solar cells (QDSSCs). The study found that the top journal for these publications was Electrochemical Acta, which accounted for 6.48% of the total publications. The most scientifically productive nations were China (47.4%), South Korea (12.3%), and India (9%), respectively. Zhong et al. (2021)

[19]

found that China had the highest number of publications (2,233) and an H-index of 119. The USA secured the second position in terms of quality of the research. The first position was in Liu Y 106 publications and Hardman R co-citations (304).

Further studies by Wang, Shen and Zhou (2021)

[20]

conducted a bibliometric analysis of quantum computing from 2016 to 2020. The study found that the United States and China had the highest scholarly output, with 7,272 and 6,272 publications, respectively. The most cited authors were Jianwei Pan of the University of Science and Technology of China, with 3,293 documents, and Mikhail D. Lukin of Harvard University, with 3,293 cited documents. Gupta et al. 2021)

[21]

found that China and the USA are at the forefront of global Quantum Communication & Networking (QCN) research, contributing 37.82% and 17.92% of the world's share, respectively. The leading organizations in the collaborative network include Österreichische Academic der Wissenschaften in Austria (97), the University of Vienna, Austria (85), and the University of Science and Technology of China (71).

In some studies on innovations, Gupta et al. (2022)

[22]

found that India contributed 2,108 publications to quantum optics research, constituting 3.13% of the world's share and 30% of publications with funding support. The Indian Institute of Science, Bangalore (96 publications), and the University of Calcutta (80 publications) secured the first and second positions, respectively. Gupta et al. (2021)

[23]

examined quantum cryptography research output from 1992 to 2019. The study found an annual average growth rate of 24.76% and an average of 23.01 citations per paper (CPP). The researchers also identified that China leads the global ranking of top countries with a 27.65% share, followed by the USA with a 17.92% share. In quantum machine learning, Dhawan (2021)

[24]

explored integrating quantum technology into other domains. Scheidsteger et al. (2021)

[25]

conducted a citation analysis on quantum dots literature Rajendran and Jeyshankar (2022)

[26]

. They used similar approaches for knowledge domain visualization and social network analysis. These studies were particularly important for the research output of the Web of Science database between 2000 and May 2011, as noted by Ding et al. (2001)

[27]

2. Literature Review

"Bibliometric" is described as "the application of statistical and mathematical methods to books and other means of communication

[28]

. According to Ferreira

[29]

, bibliometrics is "the quantitative study of physical published units, bibliographic units, or surrogates for either". In addition, Bibliometrics involves organizing and linking fundamental information from publications, including citations, authors, co-authors, journals, and keywords, to analyze and track research development

[30]

, and bibliometric analysis uses many methodologies, such as bibliographic coupling, and co-citation network analysis, and co-occurrences analysis

[31]

. Specifically, bibliometrics is one of the most accurate interdisciplinary research fields to extend to all scientific fields

[32]

, and the bibliometric examination has been utilized in different exploration fields of development

[33]

. It is used to address and understand the intricacies of scientific areas using bibliometric tools and approaches.

[34]

However, bibliographic coupling linkages are similar approaches employed in frameworks of science mapping, and for bibliographic coupling, documents are coupled based on the number of references they share

[35]

. It is considered that the two typical methodologies used together are bibliographic coupling analysis and co-citation analysis

[36]

. In other words, bibliographic coupling happens when two documents include a third term as a reference

[37]

. The ever-growing use of bibliographic coupling has been studied in the literature for analysis in multiple research relevant to the different disciplines of science, such as the following: SMART City and Economy

[38]

; Using big data for co-innovation processes

[39]

; Nephrology publications of bibliographic coupling and co-authorship networks

[40]

. Bibliographic coupling methods now assess the similarities between two articles by counting their number of references. Articles that mention similar sources are likely to have conceptual overlap, and the more references two articles share, the stronger their relationship in a bibliographic network

[41-43]

3. Objectives of the Study

1) To determine the trendline of the quantum dots research output and citations;

2) To explore the bibliographical coupling documents in the quantum dots literature;

3) To determine the country's collaboration.

4) To determine cited reference analysis.

5) To identify the most significant of keywords and author keywords;

4. Methodology

This work aims to map and analyze the current usage of the phrase "quantum dots literature" and its bibliographic coupling and cited references on the Web of Science Core Collection. A bibliographic coupling study on the related topic of quantum dots was not discovered. This study used scoping review methodologies to examine the literature's current state of quantum dots.

5. Results

Figure 2 represents the trendline of the quantum dots research output 2014-2023. The number of papers published each year has generally decreased from 485 in 2014 to 249 in 2023, and the total citation count has also decreased over the years, from 25094 in 2014 to just 473 in 2023. Furthermore, it is observed that the average citations per paper have seen a significant decline from 51.74 in 2014 to 1.90 in 2023, indicating that fewer papers are being published, and each paper is receiving fewer citations on average. However, it is increasingly recognized that 2018 (519) publications, both the citation count (25094) and ACPP (51.74%) 2014 finally, although the trendline would likely show a downward trend over the years in terms of the number of published papers, citation counts, and ACPP

Figure 5. (A) Overlay Visualization Map of the Author Citations; (B) Overlay Visualization Map of the Author Publications.

Figure 5 (A and B) shows the author's overlay visualization mapping of bibliographic coupling in quantum dots research. A total of 17565 writers published research articles, with a minimum number of selected documents and citations per author of 5. The fractional counting approach was chosen; only 324 authors fit the criteria. However, there were 71512.51 overall link strengths and 18 clusters totaling 44975 linkages. As can be seen, there is a significant cluster of authors with high indices of bibliographic connection. There was a group of primary writers with high bibliographic coupling indices: Figure 5 (A) citation authors (yellow cluster), Figure 5 (B) citation authors' average publications (blue-green and purple clusters). Specifically, the fourth cluster of authors linked with each cluster is Medintz, Igor I, Susumu Kimihiro, Algar W. Russ, and Kim Hyungki. The remaining clusters have seven to two authors; in addition, some authors represented each cluster as Rosei Federico, Krull, Ulrich J. (cluster 1), Rogach Andrey i, Torimoto, Tuskasa (cluster 2), Koto, Nicholas A, and Kuang Hua (cluster 3)

Table 2 illustrates that nanoparticles emerge as the most frequently mentioned keyword, underscoring their significant presence within the analyzed context, with 1990 occurrences. Their significant relative influence and network structure further strengthen their significance. Moreover, nanoparticles exhibit the highest total link strength of 14986, indicating robust connections. Their centrality suggests that nanoparticles lie on many shortest paths between other keywords. Quantum dots also stand out prominently, ranking second in occurrences with 1864 mentions and relative influence. They have strong links with other terms, as seen by their high total link strength of 13910. Their centrality underscores their role in bridging different parts of the network. Nanocrystals, ranking third in relative influence, exhibit a moderate total link strength of 6140 and betweenness centrality. This indicates their importance within the network, albeit not as central as nanoparticles or quantum dots. However, their closeness centrality and PageRank fall within a similar range among the top 15 keywords, suggesting their central position despite potentially lesser direct connections or authority compared to others.

[22, 51]

6. Discussions

The article mainly aims to visualize quantum dots in the literature. Bibliographic coupling and cited reference analysis were conducted using VOSviewer and the Bibiometrix package of R to achieve the same. In the context of Bibliographic coupling, and co-citation cited reference total linked strength of documents, countries, authors, and co-citation cited reference, co-occurrence is analyzed as well as these methods were conducted on 4174 documents retrieved from the Web of Science database using Boolean searching methods.

The present study identified that the number of papers published each year has generally decreased from 485 in 2014 to 249 in 2023, and the total citation count has also decreased over the years, from 25094 in 2014 to just 473 in 2023. It is increasingly recognized that 2018 (519) publications, both the citation count (25094) and ACPP (51.74%) 2014. The study further indicated that

[22]

Quantum Optics' global output is 67,274 publications, which increased from 718 publications in 1996 to 3073 in 2021 annual average growth.

Our analyses focused exclusively on the quantum dots literature in the bibliographic coupling analysis leads to identifying leading documents; Lim, 2015 secured the highest cited document entitled: Carbon Quantum Dots (CQDs) and their Applications, from Chemical Society Reviews 44 (1) 362–381, the year 2015. They further emphasized that methodologically deviate from the conventional approach, such as quantum probability theory

[52, 53]

. Guleria & Kaur. (2021)

[54]

investigated the bibliometric analysis of ecopreneurship using VOSviewer and R Studio bibliometric, 1989-2019 and the unit analysis of bibliographic coupling for the authors that cited documents. The study found that the topmost circle, the citation score Dream (2007) in orange colour, is coupled to Cohen (2007), Meek (2010), etc., while Schaltegger (2011) in blue colour is linked to Santini (2017), Cral (2005).

The current study's primary collaborator countries and papers were China and the United States, followed by India, Germany, and Russia. Secured the first and second - position citations for China and the USA. Additionally, the number of collaborators with India is 53 countries, and the highest country total link strength is 25427.26. Yu et al., 2020

[55]

focused on identifying recent research on COVID-19 global literature 2019–2020, which was retrieved from the WOS database. The researcher identified 44 collaborators with China; the total connection strength is 487, including 838 publications. China's key partners are the United States, England, and Germany. Furthermore, in the study identified, Gupta et al. (2021)

[17]

conducted a bibliometric assessment of quantum dots research in India. The study found that China received the most citations (61,790) and the highest H-index (119). The United States placed second in both citation frequency (48,664) and H-index (112)

[56]

The study highlights the leading authors in bibliographic coupling. It was found that Figure 6 (A) citation authors (yellow cluster), Figure 6 (B) citation authors' average publications (blue-green and purple clusters). Specifically, the fourth cluster of authors linked with each cluster is Medintz, Igor I, Susumu Kimihiro, Algar W. Russ, and Kim Hyungki. Previous research (28) found that Khare A is ranked first, receiving 8463 total link strength, followed by Gupta S and Das G, who received 7347 and 4857 total link strength, respectively

[47, 57]

This research shows that a total of 156096 citation references were generated, 822 cited references were meet the threshold, and there were 7 clusters, 119670 links, and 15934.22 total link strengths. The study found that the top most cited reference, Murray CB, 1993, Journal of the American Chemical Society VII5, p. 8706, appeared to have the highest link strength (364) and citations (366). Consequently, previous research aimed at Li et al. 2014

[48, 49]

investigated bibliometric analysis of Nanosafety research (2003–2013). Carried in this study allows a significant Wick, Peter, wrote “The degree and kind of agglomeration affect carbon nanotube cytotoxicity” in Toxicology Letters in 2007. It is the most referenced publication, and the paper was mentioned 318 times between 2007 and 2014.

7. Research Implications

The findings of this study are of significant importance and have several implications:

1) Researchers: The study highlights key research areas, such as (specific areas), influential authors, and countries, helping them identify potential collaborators and important research directions.

2) Policymakers: The leading countries can guide policy decisions to foster international collaborations and funding allocations.

3) Industry Stakeholders: Understanding quantum dots research trends and key contributors can empower you to make strategic decisions from beneficial partnerships and identify promising investment opportunities.

8. Conclusion

Regarding practical ramifications, academics should perform more studies on broader issues, with findings that may benefit more stakeholders. Establishing an appropriate science and technology network among researchers worldwide may be necessary, particularly in poor countries. In terms of policy recommendations, governments around the world, including developing countries, should implement policies and programs to expand research and the network for quantum dots marketing. The approach used in this study is recommended for future research on even quantum dots. However, the further development of quantum dots research in the featured countries, such as China, the USA, India, Germany, Russia, and other countries, has now put great effort into increasing the country's collaboration.
