Abstract in another language
Sol–gel synthesis is a well-known method to synthesize metal oxides such as ZnO in a facile way. Different crystal morphologies of Al-doped ZnO were obtained by tuning the pH for the synthesis. Additionally, the influence of the morphology on the sensing properties of ZnO-based resistive gas sensors was investigated by producing sensor films which were exposed to low NO2 concentrations. The results show a high and fast sensor response with a high aspect ratio of the crystal. Furthermore, a possible crystal forming mechanism was postulated. Thus, it can be assumed that the type of Zn2+ influences the crystal form. Ethanol amine can cause a capping of certain crystal planes and enhance the growth along one axis.
