Radio-photoluminescence (RPL) is a type of radiation-induced luminescence phenomenon. In recent years, in addition to its conventional use in radiation dosimetry, it has shown promise for diverse applications such as optical memory devices and high-resolution radiation imaging. Compared to conventional dosimeters that utilize thermoluminescence (TL) or optically stimulated luminescence (OSL), RPL dosimeters offer the advantage of allowing repeated readouts without erasing the stored radiation dose information [1]. Despite these favorable characteristics, the number of materials exhibiting RPL remains limited, highlighting the need for the development of new materials with superior performance. In this study, we focused on Eu-doped NaBaPO4 ceramics as a novel RPL material and conducted a detailed investigation and evaluation of its RPL properties. The results of this study are reported herein.
