A hybrid white‐light‐emitting device (see figure) whose emission originates only from ternary nanocrystal (quantum dot) composites but whose luminance performance matches the requirements of the lighting industry is demonstrated. The bright white‐light emission is obtained by controlling the Förster energy transfer and charge‐trapping mechanisms between the different components.
