Abstract:
A light-emitting device includes an emissive layer that emits light by recombination of first charges and second charges, a first electrode from which the first charges are supplied, a second electrode located on an opposite side of the emissive layer relative to the first electrode from which the second charges are supplied, and a charge transporting layer that is located between the emissive layer and the first electrode that injects the first charges from the first electrode into the emissive layer. The charge transporting layer includes a nanoparticle layer that provides a roughened electrode interface between the first electrode and the charge transporting layer and the emissive layer includes a plurality of quantum dots in electrical contact with the first electrode and the second electrode.
