Optical properties of CdS-glass nanocomposites

CdS-glass nanocomposite included CdS nanoparticles in it have been synthesized. CdS nanoparticles in silicate glass matrix have an average diameter from 3 to 7.5 nm depending on a heat treatment regime. As was demonstrated using the methods of spectrophotometry and luminescence in the UV, visible and NIR optical ranges, optical properties of the nanocomposite significantly depends on the size of nanoparticles. The high temperature treatment has lead to increase the luminescence intensity. At the same time, the contribution of the lifetime of the slower decay component was increased.
