Abstract

The CeO₂ NPs were derived from Azadirachtaindica(A.indica) leaf extracts. The X-ray diffraction studies confirmed that synthesized CeO₂ NPs were exhibited the cubic structure. In XPS spectra, the oxidation states of each element were identified for CeO₂ NPs. The Raman active mode was observed at 461cm^-1 and this was due to the symmetrical stretching mode of the Ce-8O for CeO₂ NPs. From FESEM and TEM images, the CeO₂ NPs were exhibited spherical structure. From the EDAX spectra, the elemental compositions were identified. The optical studies were carried out using UV-Vis and Photoluminescence spectra for CeO₂ NPs respectively.
