Zinc Oxide nanoparticles were synthesized from zinc acetate by microwave irradiation method. X-ray diffraction patterns showed that the prepared samples found to exhibit hexagonal structure. Surface morphology and presence of elements have been analyzed using scanning electron microscopy and energy dispersive analysis by X-rays. The presence of stretching and bending modes in the prepared samples has been determined using Fourier transform infrared spectroscopy. Optical absorption analysis showed that the prepared samples possess band gap value around 3.02 eV. Photoluminescence spectroscopic analysis indicated a strong ultraviolet emission band at 390 nm and a weak blue - green band and weak blue emission band at 484 and 444 nm respectively.
