Abstract

A quantum dot includes a salt ligand at an outer surface thereof, the salt ligand including an anion and a cation, the cation having charge transporting properties. A light-emitting device includes an anode, a cathode, and an emissive layer disposed between the anode and the cathode, the emissive layer including multiple instances of the quantum dot. In some embodiments, the emissive layer is a crosslinked layer formed by depositing a mixture including the quantum dots on a layer, and subjecting at least a portion of the mixture to external activation stimuli to form the emissive layer including quantum dots dispersed in a crosslinked matrix.
