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.

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.

The results showed that the glass transition temperature increased with an increase in La2O3 content, and the elastic properties of the glass also improved.

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.
