摘　　要：纳米氧化锌薄膜具有光电、压电、压敏和气敏等多种性质，使其在透明导体、发光元件、太阳能电池窗口、光波导器、单色场发射显示器、高频压电转换器、微传感器等方面具有广泛的用途。ZnO是研究最早、应用最广的半导体气敏材料之一，在适宜的温度下对多种气体具有很好的灵敏性。与金属氧化物气敏材料的另外两个系列SnO2和Fe2O3相比，The ZnO nano-film was prepared by sol-hydrothermal dip coating method using ZnAc2·2H2O 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.
