摘要

In this comprehensive research, the radiation shielding and physical properties of new P/Li zinc bismuth glass containing varying amounts of xLa2O3 and yGd2O3 contents were investigated. The density increased from 2.9623 to 3.1074 g/cm3 and the molar volume decreased upon the injection of a fixed amount of La2O3 and a growing quantity of Gd2O3. Optical absorption investigations were carried out in the UV–visible range. There was a blue shift within the optical absorption edge. The values of Eg were raised and Urbach energy (Eu) was decreased with increasing doping quantity. Non-linear refractive coefficient (n2), metallization parameter (M), and the third-order non-linear optical susceptibility (χ3) were enhanced with doping. The predicted values of attenuation parameters were computed by the Phy-X program and compared with MCNP5 (Monte Carlo N-particle) simulations at energy domain 0.015–15 MeV. The simulated results were confirmed to be accurate, with the biggest relative divergence between MCNP5 simulation and Phy-x being 1.4%. In order to look into the possible applications of the suggested glass system as radiation protective materials, additional significant shielding parameters, such as (LAC), (Zeff), (MFP), (HVL), and (RPE), were also computed based on MAC values. Superior shielding properties are provided by the glass sample with 0.5% La2O3 and 1.0% Gd2O3 in comparison to the widely used radiation shields. The results indicate that the glass system that was built has a bright future in gamma shielding applications since it may be modified to suit the intended purpose.
