| Abstract: | We present experimental results on the formation of silver nanocrystals in photo-thermo-refractive glasses during heat treatment
after ultraviolet and fast-electron irradiation. We compare the optical density spectrum of samples at different stages of
heat treatment. We show that the difference in the formation kinetics of silver nanoparticles is determined by the spatial
redistribution of silver ions during electron irradiation and the change in the chemical composition of near-surface layers
of glass. |
