Abstract

This study investigates the structural, optical, and gamma-ray shielding properties of aluminum fluorosilicate glasses with the composition 45SiO₂–15Al₂O₃–10CaF₂–15Na₂O–5NaF-(10-x)SrO-xNb₂O₅ (x = 0, 5, 10 mol%). Glasses were synthesized using the melt-quenching technique and characterized via XRD, FTIR, and gamma-ray attenuation measurements. XRD confirmed the amorphous nature of all samples, with Nb₂O₅ incorporation causing a shift in the broad halo position, indicating network depolymerization. FTIR analysis revealed structural modifications in Si–O–Si and Si–O–Al linkages. The introduction of Nb₂O₅ significantly enhanced gamma-ray shielding properties, with increased mass and linear attenuation coefficients, particularly at lower energies. The effective atomic number (Zeff) and equivalent atomic number (Zeq) showed a positive correlation with Nb₂O₅ content, while the energy absorption buildup factor (EABF) exhibited composition-dependent variations. These findings demonstrate that Nb₂O₅ substitution improves radiation shielding capabilities while maintaining structural stability. The study provides a foundation for developing advanced, lightweight, and transparent radiation shielding materials, offering a viable alternative to traditional heavy-metal-based shields for use in medical, nuclear, and industrial applications.

期刊介绍： Radiation Physics and Chemistry is a multidisciplinary journal that provides a medium for publication of substantial and original papers, reviews, and short communications which focus on research and developments involving ionizing radiation in radiation physics, radiation chemistry and radiation processing. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. This could include papers that are very similar to previous publications, only with changed target substrates, employed materials, analyzed sites and experimental methods, report results without presenting new insights and/or hypothesis testing, or do not focus on the radiation effects.
