ZHANG Zhao-tao, YANG Xiao-hong, MA Yong, et al. Effects of annealing on gas sensing performance and microstructure of Ti-WO3 films[J]. 2008, (8): 39-41.DOI:
grain sizes and morphology of the Ti-WO3 films made by DC magnetron sputtering are characterized by XRD.The effects of annealing on the gas sensing performance and microstructure of the Ti-WO3 films are studied.The optimal annealing temperature and operating temperature are found out
and the mechanism of these sensors is discussed.The results show that annealing at a low temperature 450℃ can improve the gas sensing performance.The best operating temperature is about 150℃.
