Synthesis and field emission property of tetrapod-like zinc oxide nanostructures by inductive heating

Inductive heating method was used to synthesis regular tetrapod-like zinc oxide within 1 minute in the air. The synthesis of the nanostructure was interpreted by the Vapor-Solid (VS) growth mechanism. The nanostructure was verified to be pure ZnO nanostructure by X-ray diffraction (XRD) spectrum. Field emission measurement was applied to prove that it owns low turn-on field and large emission current. Tetrapod-like ZnO nanostructures synthesized in our method are technologically useful for vacuum electron devices because they could be synthesized sufficiently and rapidly in a room temperature.
