Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adom201400362-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>A monolayer of graphene strongly enhances the bi‐exciton emission efficiency</bold> 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. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh3gsnd0xc" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
