This paper reports the green synthesis of CeO2 nanoparticles by microwave irradiation method, with freshly prepared egg white. This method is simple, cost-e?ective, and environment friendly, using CeCl3.7H2O and ovalbumin in an aqueous medium. As prepared samples are characterized by XRD, TEM, SEM, FTIR, Raman and DRS. XRD and Raman studies con?rm the formation of nanoparticles. TEM result shows rectangular rod shaped polycrystalline nanoparticle formation. Thermal stability is studied using TGA results. PL studies show the various emission peaks and an intensity variation with temperature. PL results give information about the self-trapping exciton mechanism. It also gives information about the hopping of electrons from different defects level to 2p state of oxygen. From DRS results, the band gap of cerium oxide nanoparticles is found to be 3.21eV. Dielectric constant, dielectric loss & AC conductivity of the cerium oxide nanoparticles increases up to 310K and then begin to decreases due to space charge polarization e?ect at the grain boundary.
