Abstract

The optical peaks of Mn⁴⁺ ions in Y₃Al₅O₁₂ crystal are analyzed by calculating the crystal field energy levels through the complete diagonalization (of energy matrix) method based on the two-spin-orbit-parameter model. In the model, the contributions from both the spin-orbit parameter of central dⁿ ion and that of ligand ion are considered. From the calculations, the eleven observed optical peaks are assigned and explained reasonably with three adjustable parameters, and the defect structure of Mn⁴⁺ center in Y₃Al₅O₁₂ crystal is estimated.
