In 2 O 3 and In 2 O 3 :M (M = Ti or Ta) thin films were deposited on glass substrates via aerosol-assisted chemical deposition (AACVD) at 450 °C. The resulting films were characterized by a range of techniques including glancing-angle X-ray diffraction, scanning electron microscopy, wavelength dispersive analysis of X-rays, and optical transmission/reflectance studies to investigate the effect of doping on the films. The In 2 O 3 :M thin films were found to contain 6.5 and 2.3 at.% of Ti and Ta, respectively. The gas sensing properties were investigated on films deposited onto gas sensing substrates via AACVD. Tantalum doped indium oxide (In 2 O 3 :Ta) thin films showed a superior response, compared to In 2 O 3 , to a number of reducing gases (ethanol, CO, ammonia) and also the oxidizing gas NO 2 . Considerable selectivity to ethanol was observed; the greatest gas response (R/R 0 ) was 16.95 to 100 ppm ethanol. © 2012 American Chemical Society.
