Abstract :
Nanoparticles are the spearheads of the rapidly expanding field of nanotechnology. The cerium oxide nanoparticles, which consist of a cerium core surrounded by an oxygen lattice have shown promise in a number of applications. The cerium oxide nanoparticles (CeO₂ NPs) and M²⁺ doped CeO₂ NPs were prepared using the Azadirachta indica (A.indica) leaf extracts. The synthesized CeO₂ NPsand M²⁺ doped CeO₂ NPs were characterized by UV-Visible spectroscopy. The various functional groups were confirmed by FT-IR spectrum. The X-ray diffraction studies confirmed that transition metal doped CeO₂ NPs were exhibited the cubic structure. The FESEM images of shows the CeO₂ NPs have exhibited spherical structure. Elemental compositions were identified by EDAX spectra. Photoluminescence spectral analysis, small shift observed for emission of the CeO₂ NPs values as compared to that of the transition metal ions doped CeO₂ NPs emission values. The antifungal studies were performed against a candida albicans strain.
