Abstract

ZnO nanowire films were grown on stainless-steel disc with a thin layer of Au as catalyst by thermal evaporation in a vacuum chamber. Morphology of the nanowires was investigated by scanning electron microscopy, while emission site distribution images were recorded by a CCD camera. The nanowires were then used as cathodes in a luminescent tube and its turn-on and threshold voltages and fields, and DC power consumption properties were studied. The luminescent tube exhibited low operation voltage and low power consumption
