摘要
Nanostructured copper oxide (CuO) thin films were prepared by spray pyrolysis technique. X-ray diffraction was used to investigate the structural properties. Surface morphology was studied using scanning electron microscopy. Microstructure was studied using a transmission electron microscope, and energy-dispersive X-ray analysis was used to determine the elemental composition of prepared nanostructured CuO thin film. Gas-sensing performance was conducted using static gas-sensing system, at different operating temperatures in the range of 200 degrees C to 400 degrees C for the gas concentration of 100 ppm. The maximum sensitivity (S = 872) to H2S was found at the temperature of 250 degrees C. Quick response (2 s) and fast recovery (5 s) are the main features of this film.
