The growth of Gd₃Ga_2.7Al_2.3O₁₂:Ce and Gd₃Ga_2.7Al_2.3O₁₂:Ce,Mg crystals was accomplished by the laser-diode floating zone method (LDFZM) under a pressurized oxygen atmosphere. Optical, luminescence, and scintillation characterization were performed, which points to their comparable scintillation performance and lower charge trapping in the scintillation mechanism compared to commercial GAGG:Ce crystals grown by the Czochralski method. Theoretical electronic band structure calculations were performed for Gd₃Ga_2.7Al_2.3O₁₂, Gd₃Ga₅O₁₂ and Gd₃Al₅O₁₂ compositions and these are discussed in the light of the experimental results obtained.
