我们报告了在高离子传导玻璃形成系统 x(AgI)2·(1 − x)Ag2SeO4 上获得的红外和拉曼光谱，其中 x = 0.35、0.40、0.46、0.48、0.50、0.54。对于0.48(AgI)2·0.52Ag2SeO4，在室温到573 K之间的温度范围内记录了光谱，探测了材料的玻璃态、部分结晶态和熔融态。将玻璃的光谱与晶体化合物 Ag2SeO4 和 α-AgI 的光谱进行比较。目前的工作得出的结论与最近对相同材料进行中子衍射和动态电导率测量得出的结论是一致的。
We report IR and Raman spectra obtained on a highly ion-conducting glass-forming system, x(AgI)2·(1 − x)Ag2SeO4 with x = 0.35, 0.40, 0.46, 0.48, 0.50, 0.54. For 0.48(AgI)2·0.52Ag2SeO4, spectra were recorded in a temperature range between room temperature and 573 K, probing the glassy, partly crystallized, and molten states of the material. The spectra of the glasses are compared with those of the crystalline compounds Ag2SeO4 and α-AgI. Conclusions reached from the present work are consistent with those recently derived from neutron diffraction and dynamic conductivity measurements on the same materials.
