Abstract

A fully-sealed zinc oxide nanowire cold cathode flat-panel device and a LED flat-panel lighting sources with different wavelengths have been used for investigating the photo-induced effect on field emission from zinc oxide nanowires. The results show that the photo-induced effect using red, orange, yellow, and green light on the field emission from zinc oxide nanowires was not obvious, while the significant increase in field emission induced by using blue and violet light was observed. Also, the shorter the wavelength, the more significant the photo-induced effect on field emission current was.
