Scintillation properties of Ce doped Gd2Lu1(Ga,Al)5O12 single crystal grown by the micro-pulling-down method

Popis výsledku v původním jazyce

Ce: Gd2Lu1(Ga,Al)5O12 single crystals were grown by the micro-pulling down (m-PD) method. All grown crystals were yellow and transparent with 3.0 mm in diameter, 15-30 mm in length. Neither visible inclusions nor cracks were observed. Luminescence and scintillation properties were measured. The substitution at the Al3+ sites by Ga3+ and at the Lu3+ sites by Gd3+ in garnet structure has been studied. In these crystals, Ce3+ 4f-5d emission is observed with 500-530nm wavelength. The decay accelerates withincreasing Ga and Ce concentration. Ce1%: Gd2Lu1Ga3Al2O12 shows highest emission intensity. The light yield of Ce: Gd2Lu1Ga3Al2O12 sample with 3mm?x1mm size was around 24,000photon/MeV using calibration from 55Fe direct irradiation peak to APD. Scintillation decay time was around 50ns.
