High photostability and enhanced fluorescence of gold nanoclusters by silver dopingElectronic supplementary information (ESI) available. See DOI: 10.1039/c2nr30653k

Gold nanoclusters prepared with a controlled amount of Ag exhibit intense fluorescence with a quantum yield of ∼16% and a "quasi-monoexponential" long lifetime of >200 ns. Characterization of the luminescent probes indicates high photostability and easy detection in cells. Additionally,...

Zusammenfassung:Gold nanoclusters prepared with a controlled amount of Ag exhibit intense fluorescence with a quantum yield of ∼16% and a "quasi-monoexponential" long lifetime of >200 ns. Characterization of the luminescent probes indicates high photostability and easy detection in cells. Additionally, fluorescence enhancement in the presence of proteins was found. The effect of silver doping on optical properties of gold nanoclusters and their application in bioimaging.
