Spatially defined molecular emitters coupled to plasmonic nanoparticle arrays
Abstract
The precise organization of molecular and functional nanoscale building blocks is a long-standing challenge in nanoscience. In particular, overlapping molecular emission with collective optical excitations at the nanoscale can result in exquisite control over the intensity, wavelength, and direction of emitted light. This work describes how positioning molecules that are components of a crystalline material called metal–organic frameworks (MOFs) around plasmonic nanoparticle arrays can result in strongly enhanced emission at wavelengths determined by the lattice, including the splitting of spectral bands by interference effects that do not require strong lattice–molecule coupling for their interpretation. This hybrid platform provides a framework for both spatially and temporally enhancing the properties of luminescent MOFs.
