In the paper methods of thermoluminescence (TSL) and time-resolved spectroscopy were used for investigation of shallow electron traps near edge of 4f⁰ band in CeO₂ and nonstoichiometric CeO₂₋x nanocrystals. It was shown that presence of the electronic traps located about 0.2 eV lower than the bottom...
