Sm-doped Al6Si2O13 ceramics was synthesized, and radiophotoluminescence (RPL) properties were evaluated. After irradiation with X-ray, the new emission lines due to the 4f–4f transitions of Sm2+ ions were observed. The lower detection limit of the Sm-doped sample was 100 mGy. The Sm-doped Al6Si2O13 is a promising RPL material.
