Silver-coated nanoporous gold skeletons for fluorescence amplification

摘要

We studied metal-enhanced fluorescence properties on the electrochemically grown nanoporous plasmonic metal skeletons. The fluorophores near the nanoporous gold substrate showed similar to 50 times emission enhancement for green fluorescent dye after simple silver coating. The observed fluorescence enhancement at the local hot spots is attributed to enhanced absorption and accelerated radiative recombination processes. (C) 2016 Elsevier Inc. All rights reserved.
