Abstract

This paper describes measurements of the R-line emission from Cr³⁺ ions in Y₃Ga₅O₁₂, Gd₃Sc₂Ga₃O₁₂, and Gd₃Sc₂Al₃O₁₂. Discrete splittings of the lines are interpreted as due to disorder on the cation sublattices. Assuming statistical distributions of the cations on the different cation sublattices enables estimates to be made of the degree of non-stoichiometry in the crystals.
