摘要：

We demonstrate an improved and rapid method to synthesize uniform two-dimensional ZnO nanosheets at low temperature. These nanosheets can be prepared within an hour. The compositions and morphologies of the nanosheets produced were characterized by SEM, XRD, Raman and photoluminescence analysis. The nanosheets showed reasonably strong electron field emission properties with good reliability. Emission current density close to 0.3 mA/cm(2) was obtained. The effects of dimensions and morphologies on the field emission performance of the nanosheets are also discussed.
