摘要：

ZnO polyhedral structures were fabricated via a rapid thermal evaporation process. The ZnO nanostructures grown had faceted trumpet-like morphologies. The intensity of visible emission in photoluminescence spectra strongly related to growth temperature, indicating different concentrations of oxygen vacancy. These structures exhibited typical sensing property to gaseous ethanol. The sensing property was related to the oxygen vacancies.
