The growth process and the optical, luminescence, and scintillation characteristics of the composition-engineered Gd2.88Sc1.89Al3.23O12 (GSAG) single crystal doped with 0.1% Pr3+ and 0.1, 0.2, and 0.3% Ce3+ grown by the μ-PD method are investigated. The GSAG:Ce single-crystal scintillator grown in Mo crucible is evaluated for the first time. The comparison of the scintillation properties of GSAG:Ce using Mo and Ir technologies is presented. The effect of annealing in air and Mg2+ codoping is also discussed. In the case of the Ce dopant, the favorable combination of ultralow afterglow, fast scintillation response, and high-density host together with a cheaper preparation technology makes these materials competitive and promising for a wide range of applications.
