Ag nanopatterned arrays prepared using
periodically proton exchanged templates have been demonstrated to
support surface enhanced luminescence. Fluorescence lifetime imaging
reveals that luminescence intensity is greatest on Ag and that the
lifetime of the molecular probe is reduced, in line with a surface
enhanced luminescence mechanism. Studies establish that the substrate
simultaneously supports surface enhanced luminescence and Raman
scattering. Spatial dependence along the nanopatterned arrays shows
<7% variation in Raman scattering signal intensity, offering high
reproducibility for practical applications. Fluorophores emitting near
the plasmon absorption maxima are enhanced 4-fold.
