In this work, multiple effects of γ-ray irradiation on properties of bulk Ge–As–Se chalcogenide glasses were studied. Increased density (ρ), thermal expansion coefficient (α) and decreased optical band gap (E opt ) were observed after irradiation, depending on glass compositions. Glasses with stoichiometric (GeSe 2 ) 100−x (As 2 Se 3 ) x compositions...
