WO/2016/133864 COMPOSITIONS AND METHODS FOR THE DOWNCONVERSION OF LIGHT||WO||25.08.2016|
||PCT/US2016/018004||MASSACHUSETTS INSTITUTE OF TECHNOLOGY||CONGREVE, Daniel, N|
The present invention generally relates to composition and methods for downconverting light. In some embodiments, the composition and methods comprise an organic material, a nanocrystal, and a ligand capable of facilitating energy transfer between the organic material and the nanocrystal. In certain embodiments, the nanocrystal has a first excited energy state with an energy less than a triplet energy state of the organic material. The organic material, in some embodiments, may be aromatic and/or include one or more pi-conjugated carbon-carbon double bonds. In some cases, incident light may be absorbed by the organic material to produce two triplet excitons. The triplet excitons may then transfer to the nanocrystal via the ligand, where they can undergo recombination, resulting in the formation low energy photons.
