Light-emitting device with crosslinked emissive layer including quantum dots with ligands bonded thereto

Abstract

A light-emitting device includes an anode, a cathode, and a crosslinked emissive layer disposed between the anode and the cathode in which quantum dots are dispersed. The crosslinked layer includes a crosslinked material and quantum dots dispersed in the crosslinked mater, the quantum dots having ligands respectively bonded to the quantum dots. The quantum dots are distributed unevenly within the crosslinked material. The ligands have a concentration relative to the weight of the quantum dots of 10 to 45 wt %. A method of forming a crosslinked emissive layer of a light-emitting device in which quantum dots are dispersed includes the steps of depositing a mixture on a deposition surface and subjecting at least a portion of the mixture to an activation stimulus to crosslink the cross-linkable material.
