Abstract : Scintillation performances of carbon‐doped YAG and YAG:Ce crystals obtained by the Czochralski method under novel conditions of Ar+CO reducing atmosphere is compared to their counterparts obtained by conventional technologies. While light yield and energy resolution in YAG crystals grown under different conditions is similar, a fast luminescence decay component of 4–6 ns is observed in YAG:C grown by the new procedure. Optimization of post‐growth thermal annealing procedure of YAG:Ce,C scintillator provides the very high light yield of 28 200 phot MeV−1, and the energy resolution of 7.8–8.5% at 662 KeV
