| 摘 要： | 以载玻片为基片,依次采用溶胶凝胶、浸渍提拉和热处理方法制备掺杂锡的氧化锌薄膜气敏材料.分别采用红外光谱对氧化锌溶胶体系进行表征;扫描电子显微镜(SEM)观察氧化锌薄膜的表面形貌;主要利用电化学工作站测量极限电流与乙醇气体浓度的关系,研究掺杂氧化锡的氧化锌薄膜在常温下的乙醇气敏性能.结果表明:所成溶胶体系稳定;10层锡掺杂氧化锌薄膜晶型较完整,排列有序,在常温条件下乙醇气体含量为0～500μL/L时,极限电流与气体浓度呈现较好的线性关系;在乙醇气体含量为500μL/L时,灵敏度可高达82.39.

| Abstract: | Sn-doped ZnO thin films were prepared by sol-gel,dip-coating method and heat treatment.The zinc acetate sol were characterized by IR.The surface morphology and crystal structure of ZnO thin films were observed by SEM.The ethanol sensitive properties of the sensors made from Sn-doped ZnO thin film were studied by electrochemical workstation in the room temperature.The results showed that the formed sols were stable;the crystal of 10-layer Sn-doped ZnO thin film was complete relatively and ordered arrangement;C2H5OH gas concentration and limiting current appeared better linearity with the gas concentration of C2H5OH 0-500 μL/L in the room temperature.When the gas concentration of C2H5OH was 500 μL/L,the sensitivity could reach up to 82.39. |
