Growth and scintillation properties of perovskite single crystals

Popis výsledku v původním jazyce

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 and also for the Sr-deficient lighter analogue, the strontium zirconate SrZrO3 (SZO). Due to very high melting points, 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. Aluminum perovskites represent another important group of promising scintillation materials, but due to difficulties in crystal growth, not much attention has been paid to them so far. We decided to study the lanthanum aluminate (LaAlO3, ), whose growth is relatively. Crystal growth by the micro-pulling-down method were reported together with luminescence and scintillation properties and interplay of the luminescence phenomena.
