dc.description.abstract | The assembly of noble metal nanoparticles is an appealing means to control the plasmonic properties of nanostructures. Dimers are particularly interesting because they are a model system that can provide fundamental insights into the interactions between nanoparticles in close proximity. Here, we report a highly efficient and facile assembly method for dimers and other forms of assemblies. Gold nanoparticles (AuNPs) adsorbed on aminosilanized glass surfaces protect the silanes underneath the nanoparticles from hydrolysis. This masked desilanization allows us to prepare AuNP homodimers on glass slides with remarkably high yield (similar to 90%). The interparticle distance and accordingly, the surface plasmon coupling are readily tuned at the molecular level using self assembled monolayers of alkanedithiols. As the interparticle distance is reduced, the resonance surface plasmon coupling progressively redshifts, following the classical electromagnetic model. When the interparticle distance enters the subnanometer regime, however, the resonance band begins to blueshift and significantly broadens. The comparison of our observations with theoretical studies reveals that quantum tunneling effects play a significant role in the plasmonic response of AuNP dimers in the subnanometer gap region. The assembly method based on the masked desilanization is extendable to the formation of various other forms of nanoassemblies and thus, will further our understanding of plasmonic interactions in nanoassemblies. | - |
