Wavelength-dependent metal-enhanced fluorescence using synchronous spectral analysis
Chemical Physics Letters(2013)
摘要
The fluorescence spectrum of Au-clusters (8- and 25-atom), which covers the spectral range 350–900nm, is dramatically enhanced in the presence of plasmon supporting plate-well deposited nanoparticles. The wavelength-dependent metal-enhanced fluorescence (MEF spectrum) correlates well with the plasmon specific scattering spectrum, i.e. the synchronous scatter spectrum of the silver surface of plate wells. Our findings suggest that the synchronous scatter spectra of plasmon enhancing substrates is a good indicator of both the magnitude and the wavelength-dependence of MEF.
