The oxygen sensing properties of the membranes have been studied , the results indicate that the membranes with ru ( phen ) 3cl2 have better oxygen - sensitivity than those with ru ( bpy ) 3cl2 , and the membranes with the formamide content of 16 % ( v / v ) and ru ( phen ) 3cl2 content of 2 . 10g / l in the precursor mixture have the best structure and quality . the fiber optic gas oxygen sensor with this sensing membrane has a detection limit of 5ppm , a response time of less than 30s , excellent reproducibility and stability . ( 2 ) a new kind of organically modified oxygen - sensitive membrane based on fluorescence quenching was prepared by sol - gel method , using dds and teos as the mixed precursor , rufchenbcla as the indicator 实验证明:该类敏感膜的tan _ 0 tan值与氧气浓度存在良好的线性关系;包埋ru ( phen ) _ 3cl _ 2的凝胶膜的氧敏感性相对较好;当甲酰胺为16体积比含量, ru ( phen ) _ 3cl _ 2在前驱体中浓度为2 . 10g l时,制备的敏感膜结构和性能最佳;对气态氧检测时,该敏感膜的响应时间小于30秒,检测下限为5ppm ,具有较好的重复性和稳定性。
