Abstract

Short overview of scintillating properties of multicomponent (Lu, Y, Gd)3(Ga, Al)5O12 garnets and a comparison with properties of Ce3+- and Pr3 +- doped single or mixed rare earth aluminum garnets RE3Al5O12 where RE are Y, Lu or their mixture in asked ratio, will be presented. The highest light yield up to 27000 ph/MeV was observed on LuAG:Ce while that observed on LuAG:Pr can reach ∼20000 ph/MeV at 10 μs long shaping time. These values are almost only one half of those of well prepared multicomponent Gd3Ga3Al2O12:Ce crystal with light yield ∼50000 ph/MeV.
