Bright White‐Light‐Emitting Device from Ternary Nanocrystal Composites

Abstract

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.
