The europium doped YSH single crystal through optical floating zone (OFZ) method for the first time and the structure of as grown sample was determined through X-ray diffraction. Meanwhile the reasons for the PL and scintillation difference between YSH:Eu and Lu2O3:Eu were discussed in this paper. [Display omitted] •The europium doped YSH single crystal through optical floating zone (OFZ) method for the first time.•Successfully mastered the method of stable growth of small bulk YSH.•The structure of as grown sample was determined through X-ray diffraction.•The photoluminescence and scintillation properties of YSH:Eu were studied.•The reasons for the PL and scintillation difference between YSH:Eu and Lu2O3:Eu were discussed in this paper. Single crystal of europium doped yttria stabilized hafnia (YSH) was grown by optical floating zone method. The structure of as grown sample was determined through X-ray diffraction. Its transmission spectrum was recorded. Its photoluminescence (PL) and scintillation properties, including PL, PL decay, scintillation luminescence efficiency and afterglow level, were measured and compared with another heavy scintillator Lu2O3:Eu. The reasons for the PL and scintillation difference between YSH:Eu and Lu2O3:Eu were discussed in this paper.
