Abstract

ZnO-based ethanol gas sensors were fabricated by the painting method and their electrical and ethanol gas sensing characteristics were investigated. The ZnO-Pt (1 wt.%) film heat treated at $400^{\circ}C$, for 2 hrs. in air showed the highest sensitivity to ethanol gas in air at an operating temperature of $250^{\circ}C$ The sensitivity of the gas sensors to 1000 ppm ethanol in air at $250^{\circ}C$ was 8.7 and rising time and falling time of the gas sensors were 3.12 minutes and 25 minutes, respectively.
