Influence of External Factors on Anisotropic Growth Habit of ZnO Crystal

Monodispersed ZnO micro/nanocrystals with various morphologies were successfully prepared via a simple solution route at low temperature. The products were characterized by means of scanning electron microscopy (SEM), X-ray diffraction (XRD), high-resolution transmission electron microscope (HRTEM), and selected area electron diffraction (SAED). Results suggest a close relationship between the morphology of ZnO and the external factors. Possible mechanisms for the controllable synthesis of ZnO particles are preliminarily discussed.
