Abstract in another language
ZnO is of interest for many applications, e.g. also for gas sensing. Here, sol-gel synthesized, nanosized ZnO is investigated with regard to its room temperature NO2 sensing behavior. It is shown that both doping and UV exposure shorten the response and the recovery times of the sensors. NO2 measurements were carried out with undoped, Sn-doped, and Al-doped ZnO sensors, respectively. The Al-doped samples provide the highest NO2-response. Furthermore, the effect of dry or humid atmosphere on the sensor response was investigated. The strong humidity influence on the sensor signal almost disappears with UV exposure. Hence, UV-light, nano-sized structure, and proper doping may be the key for room temperature NO2 sensing.
