Abstract :
By analyzing the zero-field-splitting parameters a and D of Cr2+ (3d4) ion located at tetrahedral site in ZnSe
crystal, the local structure distortion and absorption spectra around Cr2+ in ZnSe: Cr2+ system have been calculated
on the basis of the complete energy matrix for the d4 configuration within the strong-filed-representation. It is
shown that there exists an expansion distortion in the local lattice structure when Cr2+ ion is doped into ZnSe
crystal. From our calculations, the distortion parameters ?R ? 0.20A and ?? ? 3.4 are determined.
