Abstract

Gadolinium‒aluminum‒gallium garnet crystals are grown with charge compositions Gd₃Al_xGa₅ _{– x}O₁₂ (x = 1–3) and Gd₃Al₂Ga₃O₁₂:Ce³⁺. The effect high-temperature annealing in air has on the optical properties of these crystals is established. It is shown that annealing does not affect the state of cerium oxidation. X-ray fluorescence reveals a deficiency of gallium in all the investigated crystals.
