Abstract

Novel glasses in a GaS-SbS-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 GaS contents. The GaS-SbS-AgI glasses possess a wide region of transmission window (0.65-14 μm). An ionic conductivity of approximately 1.01 × 10 S/cm can be obtained for a 40 (0.8SbS-0.2GaS)-60AgI glass at an ambient temperature, and the ionic conductivity increased as temperature increased. The relative activation energy of Ag conduction was also calculated. These novel glasses show potential for the combined application of infrared optics and solid electrolytes.

摘要

采用熔融淬火法制备了 GaS-SbS-AgI 体系的新型玻璃，并确定了其玻璃形成区域。玻璃中最大可溶解的 AgI 含量为 65mol%。研究了玻璃的热、光和结构性能随 AgI 和 GaS 含量的变化。GaS-SbS-AgI 玻璃具有宽的透过窗口区域（0.65-14μm）。在环境温度下，40（0.8SbS-0.2GaS）-60AgI 玻璃的离子电导率可达约 1.01×10 S/cm，并且随着温度的升高离子电导率增加。还计算了 Ag 传导的相对活化能。这些新型玻璃在红外光学和固体电解质的组合应用方面具有潜力。
