摘要：

The ZnO nano-film was prepared by sol-hydrothermal dip coating method using ZnAc2 center dot 2H(2)O as the starting material. The structure and properties of the films were characterized by AFM, XRD, UV-Vis methods. The results indicate that the ZnO particles are crystallized in the wurtzite phase, well-distributed in the films with the mean particle size of 40 nm. The gas-sensing properties of the multi-layers for alcohols with different chain lengths were measured at room temperature. The thin films exhibited high sensitivity and rapid response-recovery characteristics to these alcohol containing gases.
