摘　　要：金属氧化物半导体气敏材料因良好稳定性和优异的光电特性广泛应用于传感器领域.基于掺杂可以调控金属氧化物半导体材料的气敏性,分别以ZnCl_(2)和Zn(NO_(3))_(2)作母体,以Cu(NO_(3))_(2)作掺杂剂制备CuO-ZnO复合材料,并将其通过浸渍提拉法固定于锡掺杂玻璃光波导表面制备出CuO-ZnO复合薄膜/锡掺杂玻璃光波导传感元件;利用光波导技术测试不同原料制备的CuO-ZnO复合薄膜光波导传感元件的气敏性.结果表明,合成复合材料所使用原料以及掺杂剂用量影响传感元件的气敏性;以ZnCl_(2)作母体而制备的CuO-ZnO复合薄膜光波导传感元件的灵敏度高于Zn(NO_(3))_(2)作母体而制备出的CuO-ZnO复合薄膜光波导传感元件;CuO的掺杂提高传感元件对二甲苯气体的选择性,能够检测出体积比为1×10^(-5)的二甲苯气体.Metal oxide semiconductor gas sensing materials are widely used in the sensors fields due to its good stability and excellent optoelectronic properties.And the gas sensing properties of them can be regulated by doping.In this paper,the CuO-ZnO composite materials prepared by sol-gel method which using Cu(NO_(3))_(2)as dopant,ZnCl_(2) and Zn(NO_(3))_(2)as raw materials,respectively.And the CuO-ZnO as sensing materials prepare the CuO-ZnO composite film/tin doped glass waveguide sensor by sol-dip-coating method.The gas sensitivity of CuO-ZnO composite film optical waveguide sensors prepared from different raw materials were studied.The research results indicated that the amount of raw materials and dopants affects the gas sensitivity of sensors.The sensitivity of CuO-ZnO composite film optical waveguide sensor prepared using ZnCl_(2) raw materials is higher than that of using Zn(NO_(3))_(2)raw materials.Doping of CuO improves the selectivity of optical waveguide sensor to xylene gases,and can be detect a volume ratio of 1×10^(-5) xylene.
