Impact of the Band‐Edge Fine Structure on the Energy Transfer between Colloidal Quantum Dots. Issue 2 (27th November 2013) - Moreels, Iwan
Abstract Förster energy transfer 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.
