Abstract

A light-emitting structure includes a substrate and a plurality of sub-pixel structures over the substrate. At least one of the plurality of sub-pixel structures includes an anode, a cathode, and a combined charge transport and emissive layer disposed between the anode and the cathode. The combined charge transport and emissive layer includes quantum dots (QDs) with ligands, and nanoparticles smaller than the QDs. The QDs and the nanoparticles are dispersed in a crosslinked matrix formed at least partially from at least one crosslinkable charge transport material other than the ligands, and the combined charge transport and emissive layer is arranged with the QDs and the nanoparticles phase segregated in an upper outer surface of the crosslinkable charge transport material, with the nanoparticles arranged closer to the upper outer surface than the QDs.
