The invention relates to scintillation inorganic oxide single crystals with garnet structure, which comprise cerium and are co-alloyed with titanium and Group 2 elements. The invention makes it possible to increase the scintillation output and to enhance the energy resolution of scintillation detectors during gamma-ray quantum registration. The technical result is achieved by a single crystal with a garnet structure being co-alloyed with cerium, titanium and Group 2 elements. This single crystal is produced by the Czochralski process.
