Abstract

In the present work, using the melt quenching technique, a series of five glass samples of Lithium-Zinc boro tellurite glasses, incorporated with silver oxide and doped with Lanthanum oxide, were fabricated to analyze the influence of substituting Ag₂O and ZnO with La₂O₃ on the physical, optical, and radiation effectiveness of the produced glasses. The focus of our research is on the physical, structural, Radiation and optical properties of lithium-zinc boro-tellurite glasses, doped with La₂O₃ in amounts from 0 to 0.4 mol%, and containing a consistent Ag₂O concentration of 1 mol%. The spectral properties of the acquired glass specimens have been analysed through UV–vis absorbance data. The non-crystalline state of the synthesized glasses was validated through the XRD technique. The structural changes and the presence of borate networks (BO₃ and BO₄), tellurite networks (TeO₃ and TeO₄), and associated links were established through FTIR techniques. Our work focuses on the synthesis, characterization, of zinc oxide (ZnO) and silver oxide (Ag₂O) added glass materials for optical and radiation shielding applications. Radiation shielding properties were evaluated using the Phy-X/PSD software. Considering the measured physical parameters and the structural, optical, and shielding properties, we can say that these glasses show promise for applications in photonics, including optical amplifiers and optoelectronic devices, as well as for radiation shielding.1
