Ce-doped SrHfO3 crystals were synthesized by the floating zone (FZ) method, and their photoluminescence (PL) and scintillation properties were investigated. X-ray diffraction (XRD) measurement indicates that the samples are mainly composed of SrHfO3, but a small peak due to HfO2 is observed. In both PL and scintillation analyses, the Ce-doped samples show the emission peaking around 410 nm, whose decay time is short due to the 5d–4f transitions of Ce3+. In the undoped sample, the emission appears around 480 nm. In the afterglow curves after 2 ms X-ray irradiation, no significant concentration dependence is observed.
