Characteristics of Zinc Oxide Film Prepared by Chemical Spray Deposition as a Gas Sensor
Zinc Oxide
Chemical spray pyrolysis
Gas sensing
Electro-optical properties
Zinc oxide thin films were deposited by chemical spray pyrolysis onto glass substrates which are held at a temperature of 673 K. Some structural, electrical, optical and gas sensing properties of films were studied. The resistance of ZnO thin film exhibits a change of magnitude as the ambient gas is cycled from air to oxygen and nitrogen dioxide
