In this work, it is reported that the γ-irradiated (2.41 MGy accumulated dose) glasses As₂S₃ (∼2 mm thick) and Ge₁₅.₈As₂₁S₆₃.₂ (∼1 mm thick), both measured ∼10 years after γ-irradiation, exhibit radiation-induced optical darkening effect (i.e., long-wave shift of fundamental optical absorption edge)...
