In this study, we used aqueous solution method to synthesis ZnO nanowires(NWs) array and different element(eg. Mn, Mg…) doped ZnO NWs. Then we made the sample into single ZnO nanowire devices and ZnO NWs array device as CO sensing device. Then we measured the CO sensing under room temperature and alternating ambient between vacuum and different concentration CO gas. Different element doped device resulted in different CO responsibility.
