Claim Text:
1. A method of making a light emitting device comprising: forming an electroluminescent emissive quantum dot layer over a substrate including a first electrode, wherein a quantum dot comprises a core comprising a first semiconductor material and a shell over at least a portion of an outer surface of the core, the shell comprising a second semiconductor material, fixing the electroluminescent emissive quantum dot layer formed over the substrate, wherein fixing the layer comprises heating in a substantial absence of oxygen, exposing at least a portion of exposed surfaces of the fixed electroluminescent emissive quantum dot layer to small molecules to treat the at least a portion of the exposed quantum dot surfaces with small molecules, wherein the small molecules are in liquid state, and wherein the small molecules comprise small polar molecules in liquid state, and exposing all or a portion of exposed surfaces of the fixed electroluminescent emissive quantum dot layer to light flux in the presence of the small molecules.
