Abstract

Crystal field (CF) analysis of the energy levels scheme of Cr³⁺ ion doped in LiAl₅O₈ spinel is performed. Using the crystal structure data and exchange charge model of CF, the CF parameters were calculated and Cr³⁺ CF Hamiltonian was diagonalized in the basis set spanned by 120 wave functions of all 8 LS terms of Cr³⁺ ion. The obtained energy levels and estimated Racah parameters B and C were compared with experimental spectroscopic data for the LiAl₅O₈:Cr³⁺ crystal; good agreement has been demonstrated.
