Abstract
Nanostructures are seeking eminent pose in technological advancement due to their size and surface properties and enhanced performance over their bulk counterparts. One of the most well-known and exciting developments among them is observed in metal oxide nanoparticles. Metal oxides have unique characteristics that make them the most pied class of materials and the properties they exhibit cover almost all facets of solid-state physics and material science. Herein, we report the synthesis of Oleylamine capped ceria nanoparticles prepared via chemical precipitation method, the idiosyncratic behaviour of amines attached to the Ce3+ ions is observed. To validate the interaction of material with the photon, absorption spectra and photoluminescence studies are undertaken; the analysed band gap is around 4.445 eV. The photoluminescence measurement shows that the CeO2 nanoparticles are fluorescent in nature. The powder x-ray diffraction (PXRD) result indicates the formation of high purity ceria nanoparticles in fluorite cubic structure in amorphous phase. The crystallite size is found to be 3.00 nm calculated by Debye Scherrer’s equation. Overall the combined results serve to indicate that aminolysis reactions are proficient at computing the play of surface amines. Prepared Ceria nanoparticles are used in many applications like hydrogen evolution, photo-degradation and sensing applications.
