Abstract

The conventional melt-quenching technique has been used for preparing a new glass system having the formula 20B2O3: 10Li2O: (70-x)P2O5: xPbO where 5 ≤ x ≤ 30 mol%. The non-crystalline state of the studied samples has been proven by XRD. Investigation of the optical properties and the structural changes of the studied glass network were done by UV-VIS and ATR-FTIR spectrometers, respectively. The obtained optical band gap and refractive index helped to obtain important factors as polarizability and optical basicity. γ-ray shielding parameters including coefficients of linear attenuation and mass attenuation, half-value layer and mean free path were measured experimentally at different γ energies and matched with the theoretical calculations obtained using the mixture principle of WinXCom software. A worthy matching was obtained between the experimental and theoretical values. The outcomes reflected that the adding of PbO significantly improve the potential applications as optoelectronics and enhance the properties of γ-ray shielding in specific energy ranges.
