Zinc oxide nanoparticles with different morphologies were fabricated successfully by generating DC arc plasma of pure zinc. Different ratios of oxygen and argon gas were used as fabrication atmosphere. The morphology evolutions of ZnO nanoparticles and the effect of atmosphere components on it were investigated by changing the ratios of atmosphere components. Morphologies and structures of the fabricated samples were analyzed by XRD, SEM and TEM. Comparison between the results of this study and our previous works showed that the morphologies of nanoparticles dominantly were determined by the oxygen partial pressure. It was also shown that the total pressure which was exerted on constituent components had a less important role in final shapes of nanoparticles.
