柱状和蝌蚪状ZnO纳米结构的制备方法研究

本研究中采用直接蒸发锌粉的方法，在硅基底上制备了ZnO纳米结构。实验结果表明，温度条件分别为550℃和n600℃时可以得到ZnO纳米柱和ZnO纳米蝌蚪。Raman光谱分析知，所得的两种ZnO结构均为六角纤锌矿结构。实验中制备的纳米结构的纯度很低，缺陷很少。

On Preparative Method of Columnar or Tadpole-shaped ZnO Nanostructures

In this research, by using the thermal evaporation methods of zinc powder, the ZnO nanostructures are obtained on the silicon substrate. The result showed that under the different temperatures of 550℃and 600℃ the columnar or tadpole-shaped ZnO nanostructures can be obtained. Raman Spectrum showed that both of the two types of ZnO nanostructures have hexagonal wurtzite structure, and the ZnO nanostructures obtained has fewer defects and lower purity.
