Abstract

This study investigates the fabrication, characterization, and performance evaluation of Tb-doped Lithium borate glasses with varying compositions. The samples were synthesized by melt-quenching, forming non-crystalline networks with lithium concentrations up to 55 %. Optical characterization revealed emission peaks at 489, 545, 585, and 621 nm under X-ray and UV excitation, enabling precise measurement with photodetectors and spectrometers. The optimization of composition and further characterization of the material are discussed. The calculated Z_eff values and thermoluminescence (TL) studies confirmed the suitability of LBO(Tb) glasses for dosimetry applications. These findings highlight the material's potential for real-time tissue equivalent and TL-based dosimetry technologies.

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.
