Abstract
This paper presents acetone vapor sensing properties of WO3 thick films. In this work, the WO3 thick films were prepared by standard screen-printing method. These films were characterized by X-ray diffraction (XRD) measurements, and scanning electron microscopy (SEM). The acetone vapor sensing properties of these thick films were investigated at different operating temperature and acetone vapor concentrations. The WO3 thick films exhibit excellent acetone vapor sensing properties with the maximum sensitivity ∼456% at 300 °C in air atmosphere with fast response and recovery time.
