Indocyanine green (ICG) is widely used in medical imaging and testing. Its complex spectral behavior and low quantum yield limits some applications. We show that proximity of ICG to a metallic silver particle increases its intensity approximately 20-fold and decreases the decay time. Since the rate of photobleaching is not increased, our results suggest that ICG-silver particle complexes can yield at least 20-fold more photons per ICG molecule for improved medical imaging.
