With Ar as the diluted gas, 02 as the reactive gas and high purity zinc powder as the metallic source, the nano-ZnO structure was grown in a catalyst-free process. The crystal ZnO morphology was measured by scanning electron microscopy （SEM）. Photoluminescence （PL） spectroscopy was employed to evaluate the crystal nano-ZnO＇s properties. Effect of several parameters, such as the temperature, 02 ratio, deposition time and polarity during nanostructure growth, was also investigated.展开更多
