Abstract

Here, we report the studies of thermal treatment effect on the structural and optical properties of nanocomposites based on cadmium sulfide quantum dots embedded in a silicate matrix. An explanation of the mechanism of reversible photoinduced absorption of the nanocomposite has been given. It is found that heating at 180°C results in significant changing of nanocomposite absorption and luminescence spectra caused by structural changes of quantum dots. It is found that photoinduced optical absorption of the nanocomposite is caused by amorphous-structured cadmium sulfide quantum dots.
