Abstract
The influence of high-energetic γ-irradiation on optical transmission spectra was investigated for the ternary Ge-As-S chalcogenide glasses of stoichiometric As2S3-GeS2 and non-stoichiometric As2S3-Ge2S3 systems. Two principally different components of radiation-induced changes were studied: static (residual) and dynamic (time dependent) ones. The latter was mathematically described due to exponential and power-related functions in respect to post-irradiation periods. It was shown that quantitative features of the observed self-restoration phenomena in the irradiated glasses were tightly connected with their chemical compositions and stoichiometry.
