Abstract

In this paper we report the structural, thermal, microstructural and infrared transmission properties of iodine doped (Ge₂₀Se₁₈Te₆₂)_{100 – x}I_x (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。
