Tailoring the optical behaviour and radiation shielding competence of B2O3-TiO2-SrO-ZnO-La2O3-CeO2 glasses
摘要
The density of B2O3-TiO2-SrO-ZnO-La2O3-CeO2 glasses increases from 3.288 to 3.632 g cm− 3. The decrease in Young’s modulus (E) from 101.943 GPa to 99.253 GPa results in a reduction in overall rigidity. The band gap energy (Eg) decreases from 3.351 eV to 3.208 eV. The refractive index (n) increases from 2.308 to 2.343. This suggests an increase in enhanced polarizability. The shielding competence has been theoretically assessed from 0.015 to 15 MeV using the Phy-X/PSD computational platform. Evaluations of fundamental shielding parameters show that shielding performance improves with increasing ZnO content. The LCZn29 sample exhibited the lowest MFP and HVL across all samples, confirming its superior efficacy and significant promise as a material for gamma-ray shielding in intermediate-energy ranges.
