Abstract :
Zinc oxide nanoparticles were synthesized by green chemistry method. Formations of nanoparticles were characterized by various spectroscopic analysis. Synthesized that nanoparticles exhibits nano flower like structure using X-ray diffraction pattern. Morphology and chemical composition were identified through field emission scanning electron microscopy and energy dispersive x-ray analysis spectra. In the case of Fourier transform infra-red spectra, the Zinc oxide vibration observed at 618 cm-1 for ZnO NPs. Optical study was determined by and PL spectra. Diamagnetic behavior was observed synthesized ZnO NPs using VSM analysis. The native defect was identified by EPR studies. The antibacterial properties of the ZnO NPs were examined by Gram positive and Gram negative strains.
