Abstract

The optical and scintillation characteristics of Gd₂YAl₂Ga₃O₁₂:Ce and Lu₂YAl₂Ga₃O₁₂:Ce single crystals are investigated. At 662 keV γ-rays, light yield (LY) of 37,900 ph/MeV and energy resolution of 7.0% obtained for Gd₂YAl₂Ga₃O₁₂:Ce are superior to those of 18,900 ph/MeV and 11.5% obtained for Lu₂YAl₂Ga₃O₁₂:Ce. Scintillation decays are measured using the time-correlated single photon counting technique. A fast component decay time of 45 ns with relative intensity of 88% obtained for Lu₂YAl₂Ga₃O₁₂:Ce is superior to that of 50 ns (65%) for Gd₂YAl₂Ga₃O₁₂:Ce. The linear attenuation coefficient at 662 keV γ-rays is also determined and discussed.
