Abstract
The aim of this paper is to make a crystal field analysis of the energy levels structure for the title materials. We report on the detailed and consistent crystal field analysis of Co 2+ spectra in both materials, which was performed in the framework of the exchange charge model of crystal field. Overlap integrals between Co2+ and O2- ions were calculated numerically and Co2+ electron density moments were evaluated. The energy level schemes for each material are obtained and compared with each other. Comparison of the theoretical results with the experimental data yields satisfactory agreement.
