Abstract

original image

Good things come in threes: A new type of light emitting bio-composites allowing for the nanometric separation of the active components is demonstrated. A protein with large host–guest capacities is used for the encapsulation of a water-soluble composite dye in a nano-sized shell, which efficiently reduces Förster resonance energy transfer and related mechanisms. Blending of this bio-composite with multi-walled nanotubes increases the charge injection efficiency, in the electro-luminescent device.
