This paper presents acetone vapor sensing properties of WO(3) thick films. In this work, the WO(3) 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 WO(3) thick films exhibit excellent acetone vapor sensing properties with the maximum sensitivity approximately 456% at 300 degrees C in air atmosphere with fast response and recovery time.
