| 摘 要： | 为了研究发光电位在0.20 V(vs.Ag/AgCl)左右的Ru(bpy)32+阴极电化学发光行为的机理,改善此电化学发光体系的灵敏度和重现性,考察了电位扫描圈数、扫描范围对此阴极电化学发光行为的影响。结果表明,Au和Nafion在这种独特的阴极电化学发光中起了关键的作用。基于实验结果,提出了一种可能的激发模式,并应用此激发模式对一些电化学发光现象进行了解释。

| Abstract: | An understanding of the mechanism of the Ru (bpy)_3~(2+) cathodic ECL behavior at about 0. 20 V (vs. Age/AgCl) is very significant for designing and selecting new coreactants, and improving the sensitivity and reproducibility of the ECL system. Here, the effect of scanning cycles and potential ranges on the cathodic ECL behavior were studied. The experimental results show that the Au and Nafion play the key roles in this cathodic ECL emission. A possible emission mode is proposed. Additionally, some interesting ECL phenomena are explained by this proposed mechanism. |
