A Ce-doped (Gd2Y)(Ga3Al2)O-12 ceramic with good performance was fabricated by sintering in an oxygen atmosphere and hot isostatic pressing. The microstructure as well as the optical and scintillation characteristics of the ceramic was investigated. The ceramic exhibited a high transmittance of 78% in the range of 500-800 nm. The radioluminescence intensity of the ceramic reached up to 30 times that of a bismuth germinate single crystal, and the light yield within 750 ns shaping time was approximately 25800 photons/MeV under (CS)-C-137 gamma-ray irradiation.
