Radio-photoluminescence (RPL) is a phenomenon in which new luminescence center is generated by ionizing radiation. It is applied, RPL materials utilized radiation indused fluorophors. In this study, since RPL had showed in Eu-doped SrAl₂O₄ that is well-known phosphor, we found RPL properties in this material. As a result, we cofiremed that this material showed high-sensitivity.
