    Abstract: Nanophosphors in the amorphous state were produced for the first time by pulsed electron beam evaporation of micrometer-sized polycrystalline phosphors of the composition Ca2Y8 (SiO4)6O2: Eu. It was found that the Raman spectrum is modified and the forbidden band width of the samples increases when the particle size lowers from micro- to nanodimens... Show More
