Radiophotoluminescence (RPL), a type of radiation-induced luminescence phenomenon, has recently attracted significant attention for its potential applications in diverse fields, including optical memory devices and high-resolution radiation imaging. In particular, RPL-based dosimeters offer a distinct advantage due to their capability for non-destructive readout. However, since the reporting of materials exhibiting practical RPL responses remains limited, there is a strong demand for exploring novel RPL materials with superior characteristics. In this study, we focused on Eu-doped K2BaSr(PO4)2 ceramics as a promising candidate for new RPL materials, and investigated as well as evaluated the dependence of their RPL characteristics on Eu concentration.
