Abstract

The response of screen-printed thick-films of NiO/TiO2 to organic solvent vapours was studied. It was found that these films displayed a significant resistance change in response to the vapours even at room temperature. The sensors displayed an inherent selectivity, proving most sensitive to toluene and propanol vapour; with comparatively low responses exhibited towards ethanol and methanol vapours. Very fast response and recovery times of 9s and 16s respectively were recorded for the devices upon exposure to 4,000ppm step changes in propanol concentration.
