Structural and physical properties of Ge11.5As24S64.5·xSe64.5·(1−x) glasses

Abstract We replaced Se in Ge 11.5 As 24 Se 64.5 glasses with S, and prepared several Ge 11.5 As 24 S 64.5 · x Se 64.5 · (1 − x) glasses with x = 0, 25%, 50%, 75% and 100%, respectively, in order to improve the laser damage threshold in the glasses. Through the results of various measurements, we concluded that the substitution of Se with S in the glasses has negligible effect on glass transition temperature T g and elastic properties. However, this could change the optical band gap and linear and nonlinear refractive indices of the glasses and significantly improve the laser damage threshold.
