Summary: High transparency radiation shielding materials and luminescence materials with stoichiometric ratio of xGd2O3:10La2O3:10ZnO:(79-x) B2O3: 1Sm2O3 (x = 0, 5, 10, 15, and 20 mol%) were developed using melt quenching technique. The physio-optical properties of the glasses, including molar volume, density, concentration of rare-earth ions, polaron radius, inter-ionic radius, optical basicity, average distance between rare-earth ions, and optical packing density, were evaluated. The glass samples exhibited high density, which is important for radiation shielding. The absorption spectra showed significant bands of Sm3+ ions. The glasses doped with Gd2O3 content of 10 mol%, 15 mol%, and 20 mol% showed better performance than X-ray windows at 10 kVp.

Summary: The study focuses on the radiation shielding properties of telluro-borate glasses in the (70-x)B2O3-5TeO2-20SrO-5ZnO-xBi2O3 system. The glassy surfaces were confirmed to be amorphous through scanning electron microscope (SEM) analysis, showing no agglomeration. Thermal differential analysis (DTA) revealed a decrease in the glass transition temperature (Tg) from 589.90°C to 529.51°C with the substitution of B2O3 mol% by Bi2O3 mol%. The mechanical properties were evaluated, and the radiation shielding properties were assessed, with the glass containing x 1/4 15% showing the highest effective atomic number (Zeff).

Summary: This study explored the radiation protection capabilities of basalt glasses modified with different concentrations of Bi2O3. Basalt-Bi2O3 glasses with the chemical composition of Basalt (100-x)-x Bi2O3, where x = 0, 10, 20, 30, 40, and 50 wt% represent G1, G2, G3, G4, G5, and G6 glasses, respectively, were used. The radiation shielding properties of the glasses were measured for gamma energies of 303 keV, 356 keV, and 662 keV using a high-resolution gamma-ray spectrometer equipped with a high-purity germanium (HPGe) detector. It was found that the addition of Bi2O3 enhanced the radiation shielding properties of basalt-based glasses and effectively mitigated the phase separation mechanism's impact on shielding.

Summary: This investigation evaluated the structural, optical, and radiation-shielding effectiveness of glasses with the xLa(2)O(3)-(20 - x) TiO2-23SiO(2)-57B(2)O(3) formula. The addition of La2O3 content significantly increased the density, refractive index, ion concentration, and field strength. Optical spectroscopy showed that the indirect optical band gap (E-opt) decreased and the Urbach energy (E-u) increased with La2O3 content. FTIR spectra detected the conversion of BO3 into BO4 tetrahedral units. The glass sample demonstrated superior gamma radiation- and neutron-shielding performance compared to other glasses.

Summary: Glasses with different BaO content in the formulation 15TiO2-70P2O5-(15-x)Li2O-xBaO (0 < x < 10 mol. %) were fabricated using the melt quenching procedure. The density of the glasses increased and the molar volume decreased with increasing BaO concentration. Ultrasonic velocities (VL & VT) increased as the amount of BaO content increased, indicating higher elastic properties. BaO content was found to be the only factor affecting the radiation shielding phenomenon in the glasses. BaO reinforcement not only increased the density of the glass compositions, but also enhanced their mechanical and gamma-ray shielding properties.
