Abstract

Pr: (Lu,Y)₃(Ga,Al)₅O₁₂ single crystals were grown by the micro-pulling down (μ-PD) method. Luminescence and scintillation properties were measured. The substitution phenomenon in the Lu³⁺ sites with Y³⁺ and Al³⁺ sites with Ga ³⁺ in garnet structure has been studied. Pr³⁺ 5d-4f emission within 300-400nm accompanied by weak Pr³⁺ 4f-4f emission in 480-650nm are observed in Ga 0-60 at.% substituted samples. Ga 80 at.% substituted sample shows only Pr³⁺ 4f-4f emission. The light output of Pr1%:Lu₂Y₁Ga₂Al₂O₁₂ sample was almost same as that of Cz grown Pr:LuAG standard. Two-component scintillation decay shows 17.9ns (93%) and 68.0ns (7%) using the PMT and digital oscilloscope TDS5032B. Slower decay components are reduced by Ga and Y substitution in LuAG structure.
