Abstract

Optical and scintillation properties of LuGd₂Al₂Ga₃O₁₂:Ce, Lu₂GdAl₂Ga₃O₁₂:Ce, and Lu₂YAl₂Ga₃O₁₂:Ce single crystals are compared. The blue-shift of 5d₁→ 4f photoluminescence emission (PL) band is observed upon partial substitution of Gd³⁺ with a smaller Lu³⁺ (or Y³⁺) ion. At 662 keV γ-rays, the light yield of 35,400 ± 1,700 ph/MeV obtained for LuGd₂Al₂Ga₃O₁₂:Ce is higher than that of 29,200 ± 1,500 ph/MeV and 20,200 ± 1,000 ph/MeV for Lu₂GdAl₂Ga₃O₁₂:Ce and Lu₂YAl₂Ga₃O₁₂:Ce, respectively. Scintillation decays are approximated by sum of exponentials with the fast component decay time and relative intensity of 78 ns (42%) for LuGd₂Al₂Ga₃O₁₂:Ce, 48 ns (71%) for Lu₂GdAl₂Ga₃O₁₂:Ce and 45 ns (88%) for Lu₂YAl₂Ga₃O₁₂:Ce, which leads to a superior coincidence time resolution of Lu₂YAl₂Ga₃O₁₂:Ce. PL decay time at 110 K and 290 K, afterglow characteristics, and mass attenuation coefficient at 59.5 keV and 662 keV γ - rays are also presented.
