In situ SiO(2)-doped SnO(2) thin films have been prepared by liquid phase deposition method. The effect of SiO(2) additive on the surface morphology and crystalline structural of the thin films were investigated by grazing incident angle X-ray diffraction (GIAXRD) and scanning electron microscopy (SEM). In the characteristics of sensing response, the SiO(2)-doped CuO-Au-SnO(2) gas sensors (Si/Sn = 0.25 and 0.33) have greater sensitivity and shorter response time than CuO-Au-SnO(2) gas sensor. However, the doped CuO-Au-SnO(2) gas sensors (Si/Sn = 0.33) can obtained better sensitivity ( S = 67 for 2ppm) and response time (t90% < 3 s).
