| Abstract: | Optical spectra in UV, visible and near IR wave-length range have been measured and the SCF X∝SW method calculation of Co3O4 electronic structure has been carried out. The nature of absorption bands observed has been revealed. As shown, the principal peculiarity of the nonstoichiometric films electronic structure compared with “bulk” samples is a stabilization of Co(III) ions high-spin configuration in Co3O4 spinel octahedral sublattice. |
