XRD, SEM, Thermal and Optical Properties of TeO 2 -ZnCl 2 -Nb 2 O 5 -TiO 2 Based Glass System According to Preparation Temperatures

Abstract

The objective of this study is to design a unique glass network composed of TeO2-ZnCl2-Nb2O5-TiO2 to investigate the optical, thermal and microstructural properties. In this experiment, the proposed glass network was produced using melt quenching method. The optical properties and optical band-gap was derived from the UV-VIS spectrophotometry experiment. Following the optical properties, the thermal and microstructural properties including the melting point and the transition phase was calculated through Differential Thermal Analysis (DTA/DSC), X-ray diffraction (XRD) and Scanning Electron Microscope (SEM-EDX). Optical bandgap energy (Eg) was computed using the range of 400nm-800nm wavelength. The estimated optical bandgap of the prepared glass samples varied from 2.60 eV up to 2.88 eV. As a conclusion, tellurite based oxide glass materials have become very much promising candidate in the areas like fiber optics, optical communication, white LED, quantum dot, quantum computing, laser technology, photonics and many other applications.
