In the present study, we investigated the photoluminescence (PL) and scintillation properties of Sm:CaHfO3. All Sm:CaHfO3 samples showed multiple PL emission peaks due to the 4f–4f transitions of Sm3+. Additionally, the PL quantum yield of 0.5% Sm:CaHfO3 was 62.8% under excitation at 410 nm, and the value was the highest among the samples. Under X-ray irradiation, all the samples showed emission peaks due to the 4f–4f transitions of Sm3+. Afterglow levels at 20 ms after 2 ms X-ray irradiation were 6000–22000 ppm.
