氯或氯化物通常用作脱水剂，用于在制备高纯度硫属化物玻璃时去除O-H或S（Se）-H。然而，一些稀土离子掺杂的硫系玻璃中的残留氯被发现对荧光发射有很大的负面影响。本文定量研究了（Ge）GaAsSbS系列玻璃中残余氯对Dy ~（3+）离子荧光发射的影响，并对其原因进行了讨论。使用Cl 2气体和SbCl 3作为氯源，并分别通过后蒸馏工艺和添加量控制其残留含量。研究结果为消除氯离子的负面影响，提高玻璃的光学增益性能提供了参考。
Chlorine or chlorides are usually used as a dehydrating agent for removing the O‐H or S(Se)‐H in the preparation of high‐purity chalcogenide glasses. However, the residual chlorine in some rare‐earth ions doped chalcogenide glasses was found to have a great negative impact on fluorescence emission. In this work, the effect of residual chlorine on the fluorescence emission of Dy3+ions in serial (Ge)GaAsSbS glasses was studied quantitatively, and the reasons were discussed. Cl2gas and SbCl3were used as the source of chlorine and their residual contents were controlled by the post‐distillation process and added content, respectively. The results can give some suggestions for how to eliminate the negative effects of chlorine and improve the glass’ optical gain properties.
