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 (Ce ) 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.
采用熔融淬火法制备了一系列碲酸盐玻璃。研究了铈对钡碲酸盐玻璃样品物理、热、结构、光学、光谱和屏蔽性能的影响。观察到随着铈离子(Ce )浓度的增加,热稳定性因子增加。利用阿基米德原理计算密度和其他物理参数,如离子浓度和摩尔体积。光学带隙和密度的增加表明非桥氧的减少。这些结果与拉曼结果一致。根据国际照明委员会色度坐标研究了制备玻璃中的蓝色发射。此外,还确定了各种屏蔽性能,如质量衰减系数、线性衰减系数、有效原子数、半价层和十分之一层,以了解所制备玻璃样品的光子屏蔽特性。
