Abstract
A light-emitting device includes an anode; a cathode; and an emissive layer disposed between the anode and the cathode, the emissive layer including quantum dots dispersed in a crosslinked matrix formed from one or more crosslinkable charge transport materials. A method of forming the emissive layer of a light-emitting device includes depositing a mixture including quantum dots and one or more crosslinkable charge transport materials on a layer; and subjecting at least a portion of the mixture to UV activation to form an emissive layer including quantum dots dispersed in a crosslinked matrix.
