Abstract:

NiO nanocrystals with the average size of 5, 10 and 25 nm were synthesized by gas-condensation method. The well-defined increase of the optical density D near the fundamental absorption edge of NiO nanocrystals in the range of 3.5-4.0 eV observed after the annealing in air is caused by the oxygen content growth, It is the direct experimental evidence of the fact that p-d charge transfer transitions form the fundamental absorption edge.
