This work reports the analysis of the distribution of Gd atoms and the quantification of O vacancies applied to individual CeO 2 and Gd‐doped CeO 2 nanocrystals by electron energy‐loss spectroscopy. The concentration of O vacancies measured on the undoped system (6.3±2.6 %) matches the expected value given the typical Ce 3+ content previously reported for CeO 2 nanoparticles. The doped nanoparticles have an uneven distribution of dopant atoms and an atypical amount of O vacant sites (37.7±4.1 %). The measured decrease of the O content induced by Gd doping cannot be explained solely by the charge balance including Ce 3+ and Gd 3+ ions.
