摘要

A series of the Calcium incorporated Barium borate glasses was fabricated via the conventional melt-quench process with the unique chemical formulation (in wt%) 44B2O3 + 20BaO + 15CaO + 20 M + 1Pr2O3 (where M = LiF, ZnF2, MgF2, SrF2, KF, CdF2) to examine the physical, structural, optical and shielding properties. The structural examinations were carried out by XRD and FTIR techniques to affirm the non-crystalline phase of the prepared samples and to discover the occurrence of stretching and bending vibrations of functional groups respectively. The physical, structural and mechanical properties were evaluated. Furthermore, the ionic and covalent character of glasses were also investigated. The UV–Vis-NIR absorption studies offered critical insights into their optical attributes, including direct, indirect energy band gap and Urbach’s energy (∆E) values. The low ∆E values suggested a minimal degree of structural disorder within the glass network. Moreover, the radiation attenuation capability of the prepared glasses was assessed using the Phy-X software. The transmission factor (TF) of the BBCLiP glass sample was investigated at various thicknesses, and the effective atomic number (Zeff) of all glass samples was analysed across different energy levels. Also, half-value layer (HVL) and mean free path (MFP) values are reported and discussed. For BBCCdP glass, RPE was found to be 59% at 0.347 MeV and HVL values ranging from 1.117 to 3.143 cm at 0.284 − 1.333 MeV. The observed lower value of TF, HVL and MFP, while the higher value of RPE and Zeff reveals the excellence radiation shielding capability of the BBCCdP glass.
