Radiophotoluminescence (RPL) is a type of radiation-induced luminescence phenomenon. In recent years, its application has been anticipated in a wide range of fields beyond just radiation dosimetry, including optical memory devices and high-resolution radiation imaging. Furthermore, dosimeters based on RPL have a significant advantage over those utilizing thermoluminescence (TL) or optically stimulated luminescence (OSL) in that the exposure information can be read out non-destructively. Despite these excellent features, the number of reported materials that exhibit RPL is relatively small, leaving room for the exploration of new materials with superior properties. In this study, we have discovered that newly developed Eu-doped Na2BrCa(PO4)2 ceramics exhibit the RPL phenomenon, and we report on the detailed investigation and evaluation of their RPL characteristics.
