- Abstract
Six crystal field energy levels obtained from the photoluminescence spectra of Yb3+-doped CuInS2 semiconductor crystal are calculated from the diagonalization (of energy matrix) method. The root-mean-square (r.m.s) deviation σ is 4.5 cm-1 and so the calculated results are in good agreement with the experimental values. The local tetragonal distortion angle θ for the Yb3+ center in CuInS2 (which is different from the corresponding angle θh in the host crystal) is obtained from the calculation.
