Abstract
The dosimetric properties of SrF2 transparent ceramics produced by spark plasma sintering with various DyF3 concentrations (0.1, 0.5, and 1.0 %) were evaluated. When excited by X-rays, they showed sharp peaks owing to the transitions between 4f levels in Dy3+ ions, in addition to a broad band related to self-trapped excitons. Thermoluminescence and optically stimulated luminescence (OSL) response were observed from all ceramics, with the 0.5 % DyF3-doped SrF2 transparent ceramic exhibiting the most intense thermoluminescence and OSL signals. The thermoluminescence minimum measurable dose was 0.01 mGy, and for OSL it was 100 mGy.
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.
