The SrHfO3 (SHO) – based perovskite scintillators have been studied since 1990’s. High efficiency and quite fast decay time were reported for Sr-deficient undoped SHO powders. Similar scintillation properties were found for the Sr-deficient lighter, the strontium zirconate SrZrO3 (SZO). Due to very high melting points (2730 °C for SHO, 2646 °C for SZO), all the research was conducted on powders or ceramics. Therefore, we prepared single crystalline samples of undoped Sr-deficient SHO and SZO using the optical floating zone method to perform a study on their luminescence and scintillation properties.
