Abstract

In this paper we report the structural, thermal, microstructural and infrared transmission properties of iodine doped (Ge20Se18Te62)100 – xIx (where x = 0, 8) chalco-halide glasses. The density of the specimen has been calculated experimentally. Differential thermal calorimetry shows a single glass transition temperature but two crystalline peaks. The role of annealing (503 and 593 K for 2 h) has also been taken into account to investigate the structural, microstructural, and infrared transmission properties. X-ray diffraction study has revealed that on annealing there is an origin of hexagonal Te and orthorhombic GeSe2 microcrystals which are further supported by scanning electron microscopy.

摘要

在本文中,我们报告了碘掺杂 (Ge 20 Se 18 Te 62 ) 100 – x I x (其中x = 0, 8) 卤化物玻璃的结构、热、微观结构和红外透射特性。试样的密度已通过实验计算。差热量热法显示单个玻璃化转变温度但有两个结晶峰。还考虑了退火(503 和 593 K,2 小时)的作用,以研究结构、微观结构和红外传输特性。X 射线衍射研究表明,退火时存在六方 Te 和正交 GeSe 2的起源 扫描电子显微镜进一步支持微晶。
