摘要：In the present work, series of silver doped Ge-Ga-S-AgI chalcohalide glasses have been prepared and their optical transmission spectra are compared before and after gamma-ray irradiation at different doses. The differential transmission spectra of the irradiated samples with and without Ag doping have been compared to characterize the gamma-ray irradiation induced red-shift of electronic absorption and formation of color centers. Ag doping plays an important role in increasing gamma-ray irradiation resistance of the chalcohalide glasses due to its specific effect on the valence band and the network structure of glasses.
