ABSTRACT
Green synthesis of zinc oxide nanoparticles and Ce ion doped ZnO nanoparticles were carried out using the leaf extract of Mangifera Indica (mango leaves). The UV-Vis spectrum 4.5eV for undoped ZnO, 4.0eV for 1% Ce: ZnO, 3.9eV for 2% Ce: ZnO, 4.0eV for 3% Ce: ZnO, 5.4eV nanoparticles. XRD behavior exhibits the size of doped and undoped ZnO nanoparticles. The crystallite size was found to 58.65 nm for ZnO nanoparticles and 49.98 nm for Ce ion doped ZnO nanoparticles. TEM micrographs also confirmed the particle size of the doped and undoped samples are in the nanoscale range and the size of the undoped ZnO and Ce ion doped ZnO nanoparticles were found to be 100 nm respectively. Green synthesis using Magnifera Indica found to be the best capping agent for synthesizing nanoparticles.
