Abstract

Hybrid nanostructures consisting of silver nanowires and photosynthetic complexes were assembled and investigated by means of fluorescence microscopy and spectroscopy, both in continuous-wave and time-resolved modes. Coupling emitters with varied spectral characteristics to plasmonic excitations in silver nanowires resulted in strong increase of fluorescence intensity and shortening of the decay times. In most cases, the emission observed at the ends of the nanowires is higher than for emitters placed along them. Overall, the results of these experiments indicate that silver nanowires are quite unique metallic nanostructures that can be used for enhancing optical properties, guiding plasmons over relatively large distances, as well as affecting the energy transfer between organic molecules.
