Abstract

A quantum dot light-emitting apparatus includes a substrate, with a first electrode layer located on the substrate. An emissive layer having a first set of quantum dots is electrically coupled with the first electrode layer, and a second electrode layer is also electrically coupled with the emissive layer. The second electrode layer is located opposite the first electrode layer, relative to the emissive layer. A first charge transport layer is placed between the emissive layer and the first electrode layer, and a second charge transport layer is placed between the emissive layer and the second electrode layer. At least one of the first charge transport layer and the second charge transport layer includes a second set of quantum dots.
