Physical, structural, elastic and optical investigations on Dy3+ ions doped boro-tellurite glasses for radiation attenuation application

S. A. Bassam et al.

Summary: A set of boro-tellurite glasses doped with Dy3+ ions were prepared using the melt quenching method, and the radiation resisting aptitude of the glasses was evaluated through various structural and elastic features. The results showed that the molar volume decreased with increasing tellurium content, indicating the presence of more bridging oxygens in the glass structure. The rigidity, density, and connectivity of the glass increased due to the rise in cross-link density. Glass with 40% TeO2 exhibited high elastic moduli and good radiation shielding properties.
