In this paper, Zinc Oxide nanoparticles are prepared by direct precipitation method. The ZnO nanoparticles are obtained after calcinations of precursor at 250ËC for 2h. Resulted nanoparticles by this method have hexagonal structure. However, their morphology is different according to used material. Nanoparticles have grate agglomeration, due to the aqueous media, which consists of nanoparticles with diameters about 7-20 nm. Fabrication of ZnO nanoparticles with different morphologies and influence of calcination temperature are studied in this work. Furthermore, DTA, IR, XRD, SEM and TEM were performed on the precursor and ZnO nanoparticles.
