Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adom201300263-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Förster energy transfer</bold> plays an important role in spectroscopic rulers, photovoltaics and solid‐state light emission, and here is a novel way of controlling it. Using a colloidal quantum dot bilayer system, it is possible to change the transfer rate while maintaining a constant efficiency. The key is a thermal exciton redistribution over the different band‐edge states, varying both the Förster and the intrinsic emission rate simultaneously. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg4sr6td2s" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
