Plasmonics: Hybrid Graphene–Giant Nanocrystal Quantum Dot Assemblies with Highly Efficient Biexciton Emission (Advanced Optical Materials 1/2015)

Year: 2015

Type: article

Abstract: When giant nanocrystal quantum dots (g-NQDs) are coupled to graphene, pairs of excitons optically excited in the g-NQDs experience efficient recombination and subsequent simultaneous emission of photon pairs. This enhancement is provided by a localized plasmon supported by a charge puddle that forms underneath the photocharged g-NQD. On page 39, H. Htoon and co-workers reveal the tremendous potential of graphene-g-NQD hybrids for lasing and entangled photon source applications.
