Preparation of ZnO nanowires for a transparent cold cathode panel and its application in light source

A transparent cold cathode panel was fabricated and applied in a double-side emitting light source using ZnO nanowire field emitter arrays(FEAs). ITO thin film coating on starting Zn film was adopted to modify the morphology and field-emission properties of ZnO nanowires. The transparent ZnO nanowire cold cathode panel shows more than 84.7% transmission in the visible light region. A fully sealed double-sided light source was fabricated.
