Abstract
A light-emitting device includes an anode, cathode, and a combined charge transport and emissive layer (CCTEL) disposed on a deposition surface between the anode and cathode. The CCTEL includes a crosslinked charge transport material and quantum dots, the quantum dots distributed unevenly within the crosslinked charge transport material and arranged relative to the deposition layer. The quantum dots include nucleophilic or electrophilic centers and ligands respectively bonded to the quantum dots. The deposition surface has nucleophilic or electrophilic properties. A method of forming the CCTEL includes the steps of depositing a mixture on a deposition surface having nucleophilic or electrophilic properties. The mixture includes a solvent, cross-linkable charge transport material, and quantum dots comprising nucleophilic or electrophilic centers and ligands respectively bonded to the quantum dots. At least a portion of the mixture to an activation stimulus to crosslink the cross-linkable material.
