    Abstract:
    The optical and radiation shielding characteristics of 15TiO2-70P2O5 - (15 - x) Li2O-x BaO x = (0 ≤ x ≤ 10 mol%) glasses were reported in this study. The glass status of the investigated samples was established by XRD. Although the molar volume decreases within 39.8-31.2 cm3 mol-1, the density was increased from 2.908 to 4.11 g cm-3 with the addition of BaO. UV-Vis-NIR spectroscopy was utilized for the examination of the optical characteristics of all compositions. E indir opt. and E dir opt. both increased from 2.7 to 3.07 eV and 2.79 to 3.31 eV, while E u decreased from 0.368 to 0.295 eV. Furthermore, the Phy-X/PSD code was used to evaluate the gamma-ray shielding parameter. Within the energy range of 15 keV to 15 MeV, the equivalent atomic number, as well as the EBF and EABF parameters, was evaluated. Overall, excellent material properties were detected for a glass with a high BaO content, which could be useful for future optical, shielding, and fast neutron shielding properties.
