摘要：

The Graphene Oxide/Polypyrrole/CdSe (GO/PPy/CdSe) nanocomposite with electrochemiluminescence (ECL) property was prepared by a novel and simple method. The composition and morphology of the nanocomposite as-prepared was characterized by a series of tests. Significantly, the electrode modified with GO/PPy/CdSe nanocomposite has strong and stable ECL emission, and can be used as ECL sensor. By studying the effect factors on ECL behavior and the ECL mechanism, it was found that the excellent ECL property of the modified electrode resulted from the synergistic effect of GO and PPy. The ECL sensor as assembled with the GO/PPy/CdSe nanocomposite was used to detect dopamine (DA), and the results show that the detection linear range for DA is from 0.01 to 16 nM with the detection limit of 0.004 nM.
