Antennas collect diffuse excitation and concentrate it at a localized receiver, allowing for a separation between energy collection and localized transformation. Converting diffuse and low intensity light into localized emitters limits parasitic reabsorption and is crucial to waveguiding and solar concentration applications. Such behavior has been leveraged across material systems, including natural and artificial photosynthetic systems, organic photovoltaics, self-assembled light-harvesting nanotubes, and quantum dot heterostructures typically involving the funneling of excitons from a large collection area to a bright emitter or reaction center. One such class of materials that may be leveraged as an optical antenna are semiconductor nanoplatelets (NPLs); which are colloidal nanocrystals that have been primarily studied for their optoelectronic properties afforded by their unique two-dimensional morphology including large absorption cross-sections, high quantum yields, directed emission, and large exciton binding energies. NPLs are often classified by number of monolayers (ML) where one ML is one layer of MX where M=Cd, Hg and one of X=S, Se, Te and commonly range from 2 to 5 ML thick. Although their thickness is only fewnanometers their lateral extent can range tens to hundreds of nm and have recently been demonstrated to micron scale. For this reason, NPLs are promising antennas due to their large lateral faces and high absorption cross-sections for exciton collection. In addition, they offer the advantage of bandgap tuneability and broad absorption across visible and near infrared spectral regions. However they require the appropriate acceptor in order to concentrate energy to a single point.
