The expression (70-x)B2O3-10ZnO-10CdO-10MgO-xBi2O3 Glasses containing B2O3, ZnO, CdO, MgO, and variable amounts of Bi2O3 were created using the melt quenching process. The observed rise in both density and molar volume of the glass samples as the Bi2O3 level increases suggests the formation of a more expanded structure with greater Bi2O3 content. There is a good degree of agreement between the observed values of band gap energy and Urbach energy estimated from the ASF model and Tauc model. The decrease in Eopt may be attributed to the increased concentration of non-bridging oxygen (NBO) inside the glass network, resulting in a disordered glass structure. The measured values of Λ and A indicate that the current glasses belong to group-II, namely typical ionic (basic) oxides. The non-linear optical properties of the current glasses, specifically n2, χ (1), and χ (3), showed an increase as the glass composition increased. The current glasses provide several benefits, such as a larger density. These glasses have a greater polarizability and an improved refractive index, making them highly sought-after materials for non-linear optical applications.

“…Rare-earth oxide such as Gd 2 O 3 has been reported to improve the physical, optical, and mechanical properties of tellurite glasses by increasing their density, refractive index, and hardness values [3]. Kaewjaeng et al [4] suggested that Gd 3+ doping reduced HVT significantly, allowing the glass to perform better than commercial X-ray windows, concrete, and bricks [5].…”
