Tuneable interplay of plasmonic and molecular excitations in self-assembled silver-fullerene nanocomposites

Popis výsledku v původním jazyce

Elaboration of functional hybrid nanostructures integrating noble metal nanoparticles (NPs) is an attractive topic in nanoplasmonics prompting unique technologies. Here we report on remarkable plasmonic properties of the self-assembled AgxC60 nanocomposite (NC) films, consisting of dense 3D-assembly of small Ag NPs and supporting C-60 medium. Systematic study of optical absorption spectra allowed us to disclose the spectral peculiarities of plasmonic and molecular excitations in the AgxC(60) NC films in the broad range of Ag concentrations, 015. We found that increase of x in the range of 0 15 demonstrate pronounced efficiency of tunnelling charge transfer plasmons. Careful analysis of the detected excitations revealed evident conformity in the x-induced alterations of the plasmonic and excitonic modes as hallmarks of plasmoneexciton interactions. The detected plasmonic effects demonstrate great potential of this metal-organic system in molecular sensing, photocatalysis and optoelectronics.
