摘　　要：用溶胶-凝胶法合成了氧化镍(NiO)溶胶,其中加入一定量的酞菁锌溶液,超声混合均匀后用旋转甩涂法固定在钾离子(K^(+))交换玻璃光波导(OWG)表面研制了酞菁锌-NiO溶胶复合薄膜/K^(+)交换光波导气敏元件并对制膜条件进行优化。该敏感元件对酸性气体(特别是对H_(2)S气体)具有较高的选择性响应,可以检测到的最低浓度为1×10^(-9) V/V_(0)的H_(2)S气体。用紫外可见分光光度计和光波导气敏性测试结果相结合,探讨了酞菁锌薄膜与H_(2)S气体之间的相互作用。The nickel oxide(NiO)sol was synthesized by sol-gel method and ultrasonic mixed with a certain amount of phthalocyanine zinc(ZnPc)solution.The ZnPc-NiO composite film optical waveguide(OWG)gas sensor was prepared on the surface of K^(+)exchanged glass OWG by using coating method.The sensor has high selectivity response to acid gas(especially to H_(2)S),and the lowest detectable concentration is 1×10^(-9) V/V_(0).Afterward,the gas sensing mechanism between the ZnPc-NiO film and H_(2)S was discussed by combining the results of UV-vis spectrophotometer and OWG test.
