Abstract

The influence of γ-irradiation on the optical properties of chalcogenide bulk glasses from both As₂S₃-Ge₂S₃ and Sb₂S₃-Ge₂S₃ sections of the corresponding glass forming regions has been studied. The “γ-darkening” e€ffect has been observed after radiation treatment by ⁶⁰Co γ-quanta with 4.4 x 10⁶ Gy dose. The changes in the optical transmission coefficient have been analyzed according to network arrangement and degree of disorder in the di€fferent compositions of chalcogenide glasses.
