Electrogenerated chemiluminescence resonance energy transfer between luminol and CdS/graphene nanocomposites and its sensing application
Electrogenerated chemiluminescence (ECL) behaviors of luminol were comparatively studied at CdS quantum dos,graphene,and CdS/graphene (CdS/GR) nanocomposites modified gold electrodes in neutral condition.The most intense anodic ECL signal was obtained at the CdS/GR nanocomposites modified gold electrode (CdS/GR/ GE).The anodic ECL of luminol (ECL-1) located at ~0.50 V (vs SCE) was increased nearly 50-times compared with the bare gold electrode.Besides,two stronger anodic ECL peaks (ECL-2 and ECL-3) were observed at 1.0 V and 1.4 V (vs SCE),respectively.The fluorescence and the UV-vis absorption spectra revealed that resonance energy transfer between luminol and CdS/GR nanocomposites was possible.The ECL spectra further demonstrated the occurrence of ECL resonance energy transfer (ECL-RET),which resulted in strong ECL-2 and ECL-3.Cytochrome C could significantly inhibit the intensities of the anodic ECL peaks,and could be sensitively detected.
