摘要

ZnO microspindles with average diameter of 200 nm and length of about 1 μm have been successfullysynthesized via a simple solution route at low temperature. The morphologies, crystal structure, chemicalcompositions of the products are characterized by scanning electron microscopy, X-ray powder diffrac-tion, transmission electron microscopy and Raman spectroscopy. It was found that the as-synthesized ZnO microspindles are single crystals with wurtzite structure and with the preferred [0 0 0 1 ] growthdirection. A strong visible emission centered at 423 nm and a weak emission at 484 nm were observed,which may be due to the defects associated to the structures. ZnO microspindles prepared here may findpotential applications in electronic and optoelectronic fields.
