The redox performance of CeO<sub>2 - x</sub> nanocrystals (nanoceria) is always accompanied by the switching of cerium oxidation state between Ce<sup>3+</sup> and Ce<sup>4+</sup>. We monitored Ce<sup>3+</sup> → Ce<sup>4+</sup> oxidation of nanoceria stimulated by oxidant in aqueous colloidal solutions controlling the luminescence of Ce<sup>3+</sup> ions located at different distances from nanoceria surface. The observed Ce<sup>3+</sup> luminescence changes indicate that Ce<sup>3+</sup> → Ce<sup> ...[more]
