A technique for the preparation of ablated particles of CeO2 of a nanosized composition has been developed. Using transmission electron microscopy and Small Angle X-ray Scattering, it has been found that the maximal particle size in a colloidal solution does not exceed 30 nm. According to Electron Energy Loss Spectroscopy, the content of oxygen vacancy defects increases with a decrease in the size of ablated nanoparticles.
