Abstract
We fabricated 20Li2O–20B2O3–60SiO2 glasses by the melt quenching method and doped Tb with a variety of concentrations from 0.03 to 3.0 %. The Tb-doped glasses showed several sharp emission peaks derived from Tb3+ in the photoluminescence (PL) and the thermally stimulated luminescence (TSL) spectra. The PL quantum yield decreased as the Tb concentration decreased. The PL decay times of the Tb-doped samples were approximately 3.0 ms which was the typical feature of Tb3+. The TSL glow peak was observed at around 75 °C, and the 1.0% Tb-doped sample indicated the highest TSL intensity. The Tb-doped samples worked as a TSL dosimeter in the range of 0.1–1000 mGy X-ray irradiation.
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.
