In the present study, tungsten oxide nanomaterials were synthesized by a modified plasma arc gas condensation technique. The effects of the plasma currents (70~90 A), chamber pressures (200~600 torr), production time(3~12 min), oxygen partial pressure Ar:O2(1~6:1)and plasma including the hydrogen(0~10 %)on the preparation of tungsten oxide nanostructures were investigated. Pre-treatment on the tungsten oxide nanorods for surface modification was investigated by atmospherical plasma jet. The optical, filed emission, and gas sensing characteristics of tungsten oxide nanopowders were also examined.
