摘要

A set of glasses was created having the composition 45 B2O3-15 SiO2-20BaF2- (20-x)Na2O- x Nd2O3, where x = 0, 0.25, 0.5, 0.75, and 1.0 mol%, in order to maximize shielding qualities. The densities of Nd-0.0, Nd-0.25, Nd-0.5, Nd-0.75, and Nd-1.0 are 3.1925, 3.2141, 3.2358, 3.2565, and 3.2778 g/cm3. The steady drop in volume per molar from 30.2589 towards 30.1747 cm3/mol further supports the denser structure. The direct band gap \({E}_{g}\) grows from 3.67615 eV towards 3.97521 eV, while indirect \({E}_{g}\) climbs from 3.33729 eV (Nd-0.0) towards 3.54197 eV (Nd-1.00). The refractive index drops to 2.26468 (Nd-1.00) from 2.31173 (Nd-0.0). The LAC was determined experimentally and calculated theoretically. The experimental values were compared by theoretical results estimated from Phy-x software and good agreement was observed. The results showed that the LACs of the Nd-glass composites gradually increased with increasing Nd₂O₃ concentration from 0.00 to 1.00 mol%, due to the increase in density. For example, at an energy of 0.060 MeV, The LAC values were 10.009 for Nd2O3 0.00 and gradually increased to 11.115 for Nd2O3 1.00, reflecting the improved attenuation capability resulting from the additive with Nd2O3.
