In the paper influence of the size on the processes of oxygen vacancies formation in CeO₂ nanocrystals has been investigated. Changes in concentration of oxygen vacancies were determined by two independent indicators: intensity of 5d → 4f luminescence of Ce³⁺ ions and ratio between ⁵D₀ → ⁷F₁ and ⁵D₀...
