The luminescence and gamma-ray detection properties of cerium-doped scintillators, namely, Lu0.3Y0.7AlO3:Ce (Lu0.3Y0.7AP:Ce), Lu0.7Y0.3AlO3:Ce (Lu0.7Y0.3AP:Ce ), and YAlO3:Ce (YAP:Ce) were investigated. UV excitation and emission spectra of studied crystals were compared. The light yield and energy resolution were measured using photomultiplier tube (PMT) readout. The light yield non-proportionality and energy resolution versus gamma-ray energy were measured and the intrinsic resolution of the crystals was determined after correcting the measured energy resolution for PMT statistics. For 662 keV gamma rays (137Cs source), YAP: Ce showed the highest light yield of 28,500 ph/MeV and the best energy resolution of 4.4 % , while its photofraction is worst.
