Abstract

In this study, ZnGa₂O₄ single crystals were synthesized and the effects of Mn doping on their fundamental optical and dosimetric properties were investigated. The Mn-doped samples exhibited a luminescence peak caused by the 3d-3d transitions of Mn²⁺ in the photoluminescence (PL) and optically stimulated luminescence (OSL) processes. Mn doping increased the PL QYs despite a decrease in the number of trapping centers. The optimal Mn concentration for PL and OSL was determined to be 0.1%. The Mn-doped ZnGa₂O₄ single crystals showed better sensitivity than a commercial C-doped Al₂O₃ dosimeter for OSL dose-response functions.

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.
