Abstract
Cerium oxide nanoparticles have been synthesized by microwave method using cerium nitrate, propylene glycol and ammonia as a precursors. The material was characterized by XRD, SEM, TEM and UV–visible techniques. XRD analysis revealed all the relevant Bragg’s reflections for face centered cubic crystal structure of cerium oxide. The average particle size was obtained 9 nm from the extrapolation of the Williamson–Hall plot. The value of particle size determined from XRD was in good agreement with the SEM and TEM results. The direct optical band gap was found to be 3.12 eV.
