摘要 为了改进以硅胶为载体的联吡啶钌对氧的响应灵敏度,采用了掺杂镧离子的硅胶做载体来固定敏感物质[Ru(bpy)3]Cl2,发现掺杂镧后样品对氧的响应倍数(I0/I)从4.6倍增大到14.4倍,响应曲线符合Stern-Volmer方程;重现性和稳定性良好;响应时间约10 s。该实验结果为发展氧传感器敏感物质的固定方法提供了一条新途径。 In order to improve the sensitivity of the oxygen sensor based on tris（2,2＇ - bipyridine） ruthenium （ Ⅱ） and [ Ru（bpy）]Cl2 adsorbed onto silica particles, the La - codoped silica gel was used as the support system. Compared with reference （ Io/I = 4.6）, The new oxygen sensor shows a high sensitivity to oxygen with a ratio of Io/I = 14.4. The response accords with Stern - Volmer equation and the codoped sample has good repeatability and photostability, with response time approximately 10 s. This is a new approach to immobilize oxygen-sensitive material for oxygen sensor.
