| Abstract: | In this paper, ZnO microcrystals with diverse morphologies were successfully fabricated via solution routes. The obtained ZnO with different morphologies, such as flower-, snow flake-, prism-, prickly sphere- and rod-like patterns, were characterized by X-ray powder diffraction(XRD) and scanning electron microscopy(SEM).The in-fluences of the solvent, temperature and pH value on the morphology of ZnO were investigated, and the possible growth mechanism was also afforded. This paper may present the promising method for the preparation of oxides with controlled morphologies. |
