摘要：

We prepared wormhole-like mesoporous tungsten oxide nanowires on a Cu-tape/Si substrate, and explored the field-emission performances. The wormhole-like mesoporous tungsten oxide nanowires of 20 nm diameter exhibited excellent field-emission properties with extremely low turn-on and threshold fields (emission current density of 10 mu A/cm(2) and 10 mA/cm(2) of 0.083 V/mu m and 1.75 V/mu m, respectively, as well as current stability of about 1400 mu A/cm(2) at a fixed field of 0.67 V/mu m. This approach provides an efficient methodology for fabricating a field emitter that is expected to work at low voltage and can be used in field-emission displays.
