Metal-enhanced fluorescence from zinc substrates can lead to spectral distortion and a wavelength dependence Academic Article uri icon

abstract

  • Metal-enhanced fluorescence enhancement factors up to 7-fold have been observed for Basic Fuchsin (BF) in close proximity to Zinc nano particulate substrates. In addition, the emission spectra of BF close-to Zinc as compared to a control sample are heavily distorted, particularly on the red-edge, giving systematic trends in enhancement, anywhere from 3-to 7- fold. We discuss these remarkable wavelength dependent effects with regard to the mechanism of metal-enhanced fluorescence.
