Effect of high temperature isothermal annealing on optical properties of Gd<sub>3</sub>Al<sub>x</sub>Ga<sub>5-x</sub>O<sub>12</sub> (x = 1—3) and Gd<sub>3</sub>Al<sub>2</sub>Ga&l
Crystals of gadolinium-aluminum-gallium garnets with the following charge compositions: Gd3AlxGa5-xO12 (x = 1—3) and Gd3Al2Ga3O12:Ce3+ were grown The influence of high-temperature annealing in air on the optical properties of these crystals has been established. It was shown that annealing does not affect the oxidation state of cerium. Using X-ray fluorescence analysis, a gallium deficiency was established in all the studied crystals.
