Hybrid Graphene–Giant Nanocrystal Quantum Dot Assemblies with Highly Efficient Biexciton Emission. Issue 1 (22nd September 2014) - Gao, Yongqian
Abstract A monolayer of graphene strongly enhances the bi‐exciton emission efficiency of CdSe/CdS core/thick‐shell nanocrystal quantum dots (NQDs), the so‐called "giant"‐NQDs. As an explanation, a new plasmon mode is proposed, resulting from local oscillations of excess hole density (the hole puddle) that is accumulated directly underneath a charged g‐NQD.
