Scintillators coupled with photon-detectors have played a major role as radiation detectors. Generally, the term "scintillator" means a single crystalline made. Today, our group try to develop transparent ceramic scintillators, as well as single crystalline scintillators. We investigate optical properties (emission and absorption spectra) and gamma-ray responses (light yield, energy resolution, and decay time) of Ce:YAG, (Ce, Nd):YAG, and Ce:GYAG ceramics, coupled with PMT and APD. For Ce:YAG, energy resolution of ∼ 6% at 662 keV is achieved when coupled with APD, and this value is better than PMT coupling. In optical properties of codoped material, there are no unexpected middle bands. The stopping power of Ce:GYAG is improved about five times large as that of Ce:YAG in several hundred keV
