dc.description.abstractThe investigation covers the thermal and linear optical properties of binary TeO2-ZnCl2 optical glass systems contain different ZnCl2 compositions ranging from 10 to 40mol%. Preparation of the glass systems were realized by melting the mixture of TeO2 and ZnCl2 chemicals in a platinum crucible at 850°C for 60 min in air. In the experiments, thermal analysis was performed to determine the thermal characteristics such as, glass transition (Tg), crystallization (Tp), and melting (Tm) temperatures for different heating rates (B=10, 20, 30 and 40 °C/min) by using the differential thermal analysis (DTA) plot. By considering the DTA plots, the crystallization activation energies were determined by using the Ozawa and modified Kissinger equations. Finally, thermal analysis show that the crystallization activation energies were 487.6kJ/mol, 215.8kJ/mol, 392.kJ/mol, and 273.3kJ/mol for the x=10, 20, 30, and 40mol% ZnCl2 contents, respectively. Optical band gaps (direct and indirect) and Urbach energies of the glass samples were estimated from the absorption spectra measured between 300 and 800nm. The direct band gap energies decrease from 3.65 eV to 3.35 eV, and indirect band gap energies also decrease from 3.59 eV to 3.30 eV by increasing the ZnCl2 content from 10 to 40 mol%, respectively. © 2015 IEEE.en_US
