White‐light emitter: A convenient and general method for the preparation of composites with pure and stable white‐light photoluminescence and electroluminescence from fluorescent nanocrystals (NCs) and functional polymers is developed (see figure; FRET=Förster resonance energy transfer)). Through electrostatic interaction the distance of the charged polymers and the NCs is shortened so that efficient electron transfer occurs at the interface.
