摘要

We successfully synthesize four kinds of ZnO nano/microcrystals including dumbbell microrods,nanoflakes,nanoplates,and microrods by a simple wet chemical method.Growth duration is found to play a crucial role in the morphologies of these ZnO nano/microcrystallites.In addition,growth conditions are systematically studied as a function of precursor concentration and temperature.The structural and optical characteristics of the ZnO samples are further investigated by X-ray diffraction,scanning electron microscopy,and photoluminescence spectroscopy.
