Abstract
In this study, Gd3+-doped NCPBZ glass-ceramics were prepared using melt-quenching technique, and their radiation dose performance was investigated. By varying the concentration of Gd3+ ions, we found that the sample with 0.5 mol% concentration exhibited the strongest luminescence and the best optically stimulated luminescence (OSL) intensity. Therefore, further OSL related tests were conducted on samples with this concentration under different doses. The results showed that the continuous wave OSL dose response fitting value of the sample in the range of 0.1–1000 Gy was m = 0.928, which is close to 1, while R2 was 0.9992 in the range of 50–1000 Gy, indicating better linearity. Meanwhile, the relative standard deviation of the OSL intensity for the sample's ten-cycle tests was 1.5%. The Gd3+-doped NaCaPO4 microcrystalline glass studied here is expected to have broad application prospects in wide-range linear radiation dose monitoring.
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.
