Aerosol Assisted Chemical Vapour Deposition (AACVD) was implemented to grow WO layers with nanoneeddle-like morphology onto gas sensor alumina substrates from a W(OPh) precursor. A variety of solvents and deposition temperatures in a range of 350°C and 500°C were used in order to find the optimal deposition conditions. The obtained WO structure was doped with gold particles by rf sputtering. The WO gas sensor based on nanoneedles showed high selectivity against to NO . The sensing properties of WO nanoneedle-like structure, as well as influence of gold doping in their sensing properties were examined in this work.
