Abstract

Photoluminescence and scintillation properties of 0.1%, 0.5%, 1.0%, and 5.0% Er:CaHfO₃ single crystals were synthesized and evaluated. The photoluminescence and scintillation spectra showed several emission peaks originating from the 4f–4f transitions of Er³⁺ in visible and near-infrared regions. Dose-rate-response of 0.5%, 1.0%, and 5.0% Er:CaHfO₃ samples showed an excellent linear relationship between dose rate and output signal intensity across the range of 0.0025–51 Gy/h. Based on the results, the 1.0% Er:CaHfO₃ sample exhibited the best performance among all the Er:CaHfO₃ samples.
