Abstract
An analysis of the efects of europium oxide (Eu2O3) on the shielding, dielectric, and struc￾tural properties of zinc lithium borate  glasses was carried out. A rise in the amount of
Eu2O3 in glasses from 0.0 to 1.0 mol% results in an improvement in density from 3.086 to
3.2176 g cm−3. FTIR analyses of our recently developed glasses revealed the production of
functional groups and units, including bridging BO4 and non-bridging BO3. Bridging BO4
rose at low concentrations of europium oxide and returning to BO3 at high concentrations
of europium oxide. The dielectric constant of all the glasses loaded with various ratios of
Eu2O3 mol% sharply decreased as frequency rose in the low-frequency range. As the Eu2O3
level increased to 0.25 mol%, the dielectric constant value frst decreased, suggesting an
improvement in BO4 and then improved at increasing concentrations. For each glass that
was examined, the indicated tan δ showed a relaxation peak at approximately 5 kHz. The
lowest tan δ was found at a level of 0.25 mol% Eu2O3. The specimen of glass altered with
0.25 Eu is a desirable choice for packing materials because of its smallest tan δ and dielec￾tric constant. The gamma-ray exposure buildup and energy absorption factors parameters
of that oxide glass system in energy region of 0.015–15 MeV up to depths of penetration of
40 mfp have been calculated by using Photon Shielding and Dosimetry (PSD) software. It
has been demonstrated that Zeq values vary on photon energy.
