Abstract :
The authors presented highly sensitive tuning of color chromaticity by controlling radiative decay kinetics and steady state emission of layer-by-layer spaced nanocrystal solids through adjusting the separation between donor and acceptor nanocrystal bilayers. Such FRET-based fine tuning offers a post-synthesis approach to control color in NC solids, alternative or additive to using the NC size, shape, and composition control. This approach can be utilized to fune the photometric properties of nanocrystal integrated white LEDs.
