Abstract

For the first time, we received and studied the spectral properties of AgCl nanocrystals in fluorine phosphate glass. It was shown that the increase of heat treatment duration leads to the long -wavelength shift of the exciton absorption band and the increase of its intensity. The average size of the AgCl nanocrystals was 2.50 - 3.70 nm. With a decrease in temperature of the glass with AgCl nanocrystals from 25°C to -196°C the shift of the maximum of the exciton absorption towards the short wavelength region took place.


Keywords: nanocrystals, fluorine phosphate glasses, exciton absorption, silver nanoparticles
