Abstract

Glass composed of (Ga₂S₃)_0.60(La₂S₃)_0.35(Er₂S₃)_0.05 and (Ga₂S₃)_0.60(La₂S₃)_0.27(Er₂S₃)_0.13 is synthesized. It is found that glass composed of (Ga₂S₃)_0.60(La₂S₃)_0.35(Er₂S₃)_0.05 softens during its thermal decomposition of in air at 855 K. In the range 945–1210 K, an exothermic effect is observed. The nature of the thermal curves indicates the stage mechanism of glass decomposition. IT is revealed that the absorption bands of glass typical for Me–S bonds are more intense and partially shifted toward the high-frequency spectrum than those for the initial crystalline components, which is apparently related to the increase in the covalence of the Ga–S and Ln–S bonds.

摘要

合成由（Ga ₂ S ₃）_0.60（La ₂ S ₃）_0.35（Er ₂ S ₃）_0.05和（Ga ₂ S ₃）_0.60（La ₂ S ₃）_0.27（Er ₂ S ₃）_0.13组成的玻璃。发现由（Ga ₂ S ₃）_0.60（La ₂ S ₃）_0.35（Er ₂ S ₃）组成的玻璃_0.05在855 K的空气中热分解过程中会软化。在945-1210 K的范围内，观察到放热效应。热曲线的性质表明玻璃分解的阶段机制。IT业已发现，与初始晶体成分相比，Me-S键典型的玻璃吸收带更强烈并且向高频频谱部分偏移，这显然与Ga-S的共价增加有关。和Ln–S债券。
