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.
