Abstract
Fluorine doped Zinc Oxide (F:ZnO) thin films were deposited on glass substrates by simple chemical spray pyrolysis technique. The effect of F doping (1 at% to 5 at %) on the ethanol gas sensing properties were studied. The Ethanol gas response is higher at the operating temperature 300 OC of the film and it is lower on either side of operating temperature. The response and recovery times of the F: ZnO films were enhanced significantly compared to those reported for ZnO films. The response of 4% F doped ZnO film to ethanol is certainly better than that others. For F doped ZnO film on exposure to 1000 ppm ethanol at 573 K, the response was increased to ethanol gas up to 4 at% while further increase in doping response was decreased. Keywords: Spray pyrolysis, F-doped ZnO films, ethanol sensing properties, response time
