Abstract :
We prepared large-area patterned tungsten oxide nanowire arrays on glass substrate by thermal oxidation method. The as-synthesized tungsten oxide nanowires have high aspect ratio up to 150. Field emission measurement shows that the tungsten oxide nanowire arrays have excellent field emission properties and good emission uniformity with a turn-on field of 6.3 V/μm.
