Study of Fluorescent Property of Gold Nanoparticles with Different Surface Structures
Fluorescence spectra of naked gold nanoparticles, triphenylphosphine stabled gold nanoparticles and 3-mercaptopropionic acid substituted gold nanoparticles were studied in this paper. It was found fluorescence intensities of gold nanoparticles were highly sensitive to surface molecules. The fluorescence quenching effect of these gold nanoparticles on CdSe nanoparticles was also investigated. This quenching effect was related to the overlap degree between the absorption spectra of gold nanoparticles and the emission spectrum of CdSe nanoparticles, and was as well as surface-dependent.
