A comprehensive study on the optical, mechanical, and radiation shielding properties of the TeO2–Li2O–GeO2 glass system.

This paper summarized a comprehensive study on mechanical, optical, and shielding features of the binary lithium-tellurite glasses as a function of doped germanium and lithium oxide content. The Makishima- Makinzie model was applied to compute and estimate the investigated glass samples' mechanical properties. The optical features are studied by determining the optical energy gap (E_g), Urbach energy (E_u) of the TLGe glass system. Both factors vary with the content of dopant germanium and lithium ions in non-linear correlation. Refractive index, molar refraction, electronic polarizability, reflectivity, reflection factor are computed for the studied glasses. The metallization and dielectric constant for the prepared glasses are estimated. The obtained results depict the variation of the optical parameters versus the GeO₂ + Li₂O content change. The investigated glasses can be suitable for applying in optical devices. The examination showed that the replacement of TeO₂ by GeO₂ + Li₂O enhances the investigated glass samples' shielding properties. The mass attenuation coefficient improved in order 41.79, 42.31, 42.91, and 42.96 cm²/g with substitution [ABSTRACT FROM AUTHOR]
