Abstract:
In this paper, a sputtering ceramic target based on SnO2 doped with 2 at.% Co was synthesized by solid-phase reaction method. A chemiresisive alcohol vapor sensor based on SnO2<Co> was manufactured by the high-frequency magnetron sputtering method. The alcohol sensing properties of the SnO2<Co> sensor under the ultraviolet (UV) illumination were examined at room temperature. The UV-assisted alcohol sensor showed a sufficient response to low concentrations of alcohol vapor at room temperature. The Co-doped SnO2 sensor has also demonstrated a good response to alcohol vapors at elevated operating temperature (200 °C).
