Study on the Absorption Spectra of Ga₂Se₃:Co²⁺ Single Crystals

Abstract

Introducing the average covalent factor N and considering the interaction of the cubic crystal field, the spin-orbit coupling and Tree's correction effects, the crystal field parameter D q was calculated. Also the varying tendency of D q with the bond length R was investigated. Using the complete diagonalizing method the energy levels of the fine structure of Ga 2 Se 3 :Co 2+ single crystal were calculated and assigned. The calculated and assigned results are consistent with the experimental data.
