Silver nanoclusters influence on formation of PbSe QDs in fluorine phosphate glasses Nа <sub>2</sub>О-Р <sub>2</sub>О <sub>5</sub>-Gа <sub>2</sub>О <sub>3</sub>-А1F <sub>3</sub>-ZnО(Se)-PbF <sub>2</sub> has been studied. Absorption spectra of the glasses containing silver nanoclusters and PbSe QDs (at diameter from 3,5 nm up to 13 nm) demonstrated a shift of the first ecxitonic peak position to the longer wavelengths than Ag-free glasses under given heat-treatment conditions. Moreover the absorption coefficients of the glasses containing silver nanoclusters and PbSe QDs are higher than ones for Ag-free glasses.
