Abstract

Pr doped (Lu,Gd)₃(Ga,Al)₅O₁₂ single crystals were grown by the micro-pulling down (μ-PD) method. The crystals were greenish and transparent with 3.0 mm in diameter, 10-30 mm in length. Neither visible inclusions nor cracks were observed. Luminescence and scintillation properties were measured. The substitution at the Al³⁺ sites by Ga³⁺ in garnet structure has been studied. The Pr³⁺ 5d-4f emission is observed within 300-380 nm wavelength superposed with 312 nm emission line of Gd³⁺. Pr0.2%:Lu_2.5Gd₁Ga₃Al₂O₁₂ shows highest emission intensity. The light yield of Pr0.2%:Lu_2.5Gd_0.5Ga₂Al₃O₁₂ sample with diameter 3 mm×1 mm size was around 8000 ph/MeV. Two-exponential approximations of scintillation decay showed 39.6 ns (30.6%) and 151 ns (69.4%) decay times.
