摘要：

Nanoplates, flower-like nanostructure of ZnO were successfully synthesized by employing ZnSO4 center dot 7H(2)O, NaOH as the starting materials at 120 degrees C under hydrothermal condition. Keeping the same parameters, ZnO urchin shape was obtained by addition of vitamin C at 190 degrees C. Characterizations were carried out by X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) at room temperature. Selected area electron diffraction (SAED) pattern confirms that the product is single crystalline nature. The possible formation mechanisms for synthesized ZnO nanosturcture with various morphologies have also been proposed. PL spectrum from the ZnO flower-like structures reveals weak UV emission and strong green emission. (c) 2007 WILEY-VCH Verlag GmbH & Co. KGaA, Wembeim.
