Abstract

In this paper, ZnO with a rich variety of well-defined morphologies have been achieved by solution route using different kind of precursors, which can prepare particles by only one step without calcination. The influences of solvent, and temperature on the particle size and morphology of ZnO were investigated. It was revealed by the scanning electron microscope (SEM) and transmission electron microscope (TEM) images that the morphological feature of ZnO can be controlled as rod-, polyhedron-, fluffy sphere-, snowflake- and flower-like, etc. XRD measurement showed that all of the ZnO samples with different morphologies has the same hexagonal structure, which is well consistent with electron diffraction (ED) characterization. This communication not only provides promising candidates for materials science due to the importance of shape in relationship with materials, but also presents an effective route to synthesize the well-defined inorganic materials.
