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.
