Abstract: Novel glasses in a Ga <subscript>2</subscript> S <subscript>3</subscript> -Sb <subscript>2</subscript> S <subscript>3</subscript> -AgI system were prepared with a melt-quenching method, and their glass-forming region was identified. The maximum dissolvable AgI in glasses was 65 mol%. The thermal, optical, and structural properties of glasses were investigated as a function of AgI and Ga <subscript>2</subscript> S <subscript>3</subscript> contents. The Ga <subscript>2</subscript> S <subscript>3</subscript> -Sb <subscript>2</subscript> S <subscript>3</subscript> -AgI glasses possess a wide region of transmission window (0.65-14 μm). An ionic conductivity of approximately 1.01 × 10 <superscript>-3</superscript> S/cm can be obtained for a 40 (0.8Sb <subscript>2</subscript> S <subscript>3</subscript> -0.2Ga <subscript>2</subscript> S <subscript>3</subscript> )-60AgI glass at an ambient temperature, and the ionic conductivity increased as temperature increased. The relative activation energy of Ag <superscript>+</superscript> conduction was also calculated. These novel glasses show potential for the combined application of infrared optics and solid electrolytes.
