Abstract

The exchange charge model of crystal field (which includes the covalent effects) is used to analyze the energy level schemes of Cr ³⁺ ion in ZnAl ₂S ₄ and ZnGa ₂0 ₄ crystals with spinel structure. Calculations of the overlap integrals and crystal field parameters were performed before getting the Cr ³⁺ energy levels. The calculated energy level schemes are compared with available experimental data; a new interpretation of the absorption peaks is suggested.
