摘要

A series of borate barium zinc sodium (BBZNL) glass system doped with lutetium oxide (Lu2O3) with the chemical composition 53B2O3 + 26BaO + 10ZnO + (11-x)Na2O + x Lu2O3 (0 ≤ x ≤ 4 mol%) were synthesized using the melt-quenching procedure. The study investigated the impact of Lu₂O₃ content on the physical, optical properties, and radiation shielding of these glasses. FTIR analysis revealed characteristic vibrational bands of borate barium zinc sodium glass. Through increasing Lu2O3 content, both the density and molar volume of the glasses increased from 3.220 to 3.553 g/cm3 and from 28.484 to 29.596 cm3/mol, respectively. The optical band gap energy (Eg) decreased from 3.43 to 3.31 eV, and from 3.34 to 3.08 eV for direct and indirect transitions respectively. The radiation shielding properties, evaluated with Phy-X/PSD software, demonstrated that the glass incorporating 4 mol% of Lu2O3 (Lu4) displayed the highest mass and linear attenuation coefficients ( \(\mu_{m}\) μ m and \(\mu_{l}\) μ l ), along with the lowest half-value layer (HVL) and tenth value layer (TVL), across a broad energy spectrum (0.015–15 MeV). A comparative analysis highlights the potential of these glasses for applications in optical and radiation shielding technologies.
