By this method, particles in colloidal solution and re-dispersible powders withspherical shape and luminescent properties were formed. The materials were characterised by High ResolutionTransmission Electron Microscopy (HRTEM) and Luminescence Spectroscopy (LS). Oxide nanoparticles 5 to 6 nm insize, with homogeneous distribution, good morphology and high crystallinity were obtained, being colloidally stable forweeks. In the case of the re-dispersible powders, nanostructured aggregates 300 to 400 nm in size were observed,containing ultra-small individual nano-oxide bcc crystallites.
