Structural, Morphological and Optical Properties: CeO2 Nanoparticles Prepared through the Azadirachta indica Leaf Extract by Green Method


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.
