Recent study revealed that single crystal Ce:Gd-3(Al,Ga)(5)O-12 (Ce:GAGG) showed good scintillation response under gamma-ray exposure. We discover here that ceramic Ce:GAGG scintillator exhibited better performance than the single crystal counterpart. We developed Ce 1% doped ceramic and single crystal GAGG scintillators with 1 mm thick and compared their properties. In radioluminescence spectra, they showed intense emission peaking at 530 nm due to Ce3+ 5d-4f transition. The Cs-137 gamma-ray induced light yields of ceramic and single crystal resulted 70000 ph/MeV and 46000 ph/MeV with primary decay times of 165 and 143 ns, respectively. At present, the observed light yield was the brightest in oxide scintillators. (C) 2013 Elsevier B.V. All rights reserved.
