Optical properties of oxide magnetic ZnO, Zn0.95Mn0.05O and Cu2O nanopowders

ZnO, Zn0.95Mn0.05O and Cu2O nanocrystals are synthesized. Excitonic lines in absorption spectra of these materials are detected. In photoluminescence and photoluminescence excitation spectra of Zn0.95Mn0.05O the dangling bond hybrid (DBH) state is found. It has splitted out from the top of the valence band due to the hybridization between d-states of the Mn impurity and the p-states of oxygen.
