Effect of KI/AgI on the thermal and optical properties of the GeS₂-In₂S₃ chalcogenide glasses.
GeS₂-In₂S₃-KI/AgI chalcohalide glasses were prepared by traditional melt-quenching method and the glass-forming region was determined. The dependence of glass properties on composition as formula of (100 - x)(0.75GeS₂-0.25In₂S₃) - x(In₂S₃-KI/AgI) was investigated. The allowed indirect transition of samples was calculated according to the classical Tauc equation. The results show that 50 mol% AgI can be introduced in the glassy matrix while only 40 mol% of KI can be incorporated in the GeS₂-In₂S₃-KI glass system. GeS₂-In₂ S₃-AgI glass system has larger density, higher refractive index and better thermal stability, while GeS₂-In₂S₃-KI glass system has shorter visible cut-off wavelength and higher optical band gap.
