Abstract

Nd 1 mol% doped (Lu, Gd)₃(Ga, Al)₅O₁₂ (LGGAG) single crystals were grown by the micro-pulling down (μ-PD) method. Luminescence and scintillation properties such as absorption, excitation and emission spectra, light yield and decay time were evaluated. Nd1%:Lu₃Al₅O₁₂ showed the highest light output of around 8200 photons/MeV among the grown crystals. Scintillation decay time of Nd:Y₃Al₅O₁₂ was 1.32 μs (36%) 2.02 μs (64%). Nd:Lu₃Ga₃Al₂O₁₂ was relatively high dense scintillator of 7.38 g/cm³ with good light yield of 6800 photons/MeV and scintillation decay time of 0.20 μs (5%) 2.60 μs (95%).
