combined structure of Ag nanowire (NW) and nanodot (ND) array. Highly enhanced
fluorescence from fluorophore is attributed to a strongly coupled optical near-field interaction
between proximately located Ag NW and NDs. We obtained enhanced fluorescence
intensity with up to 140 folds, as contrasted from background intensity, reaching a theoretical
maximum value. On the other hand, fluorescence lifetime was greatly reduced to 0.27 ns …
