Thermal, structural, optical, and photon shielding studies of cerium‐doped barium tellurite glasses

Abstract

A series of tellurite‐based glasses are prepared by using a melt‐quenching method. The effect of cerium on the physical, thermal, structural, optical, spectroscopic, and shielding properties of barium tellurite glass samples is studied. It has been observed that the thermal stability factor increases with increasing cerium ion (Ce3+) concentration. The density and other physical parameters such as ion concentration and molar volume are calculated using the Archimedes principle. An increase in optical band gap and density suggests a decrement in non‐bridging oxygens. These results are in accordance with Raman results. The blue emission in prepared glasses is studied in terms of International Commission on Illumination chromaticity coordinates. Moreover, various shielding properties such as mass attenuation coefficient, linear attenuation coefficient, effective atomic number, half‐value layer, and tenth‐value layer have also been determined to understand the photon shielding characteristics of as‐prepared glass samples.
