The features of oxygen vacancies and therefore non-stoichiometric cerium oxide formation in CeO2 nanocrystals depending on the atmosphere of high temperature treatment were investigated. Stimulation of oxygen vacancies formation in reducing and neutral atmospheres was revealed. Occurrence of two different luminescence centers (viz. the charge-transfer complexes formed by Ce4 + and O2 – ions, and Ce3 + ions stabilized by vacancies) after cerium oxide nanoparticles annealing in a neutral atmosphere has been observed.
