Abstract
The use of the APCVD reaction of WCl6 with ethanol to produce tungsten oxide films (3600-6700 nm thick) for use as gas sensors is presented. The response of these films to varying concentrations of ethanol and NO2 at varying temperatures has been examined. A comparison of the CVD sensors to a thick film (similar to 60 mu m) screen-printed sensor has shown that the CVD sensors have a faster rate of response, a stable sensing response and faster return to baseline with no drift at the conditions examined.
