Patent ID: 8618561

Claim:
A method for making a light-emitting device including an emissive material including a nanomaterial comprising quantum confined semiconductor nanocrystals that emit light having a predetermined wavelength comprising: providing a substrate including a first electrode, disposing a first layer over the substrate including the first electrode; depositing an ink comprising the nanomaterial comprising the quantum confined semiconductor nanocrystals and a liquid vehicle over a surface of the first layer from a micro-dispenser in a predetermined arrangement; and disposing a second electrode over the predetermined arrangement, wherein the first layer comprises a material which is at least partially soluble in the liquid vehicle, wherein at least a portion of the nanomaterial is at least temporarily mixed in a portion of the material that dissolves in the ink, and wherein the liquid vehicle is removed such that the nanomaterial phase separates to form a layer of nanomaterial at the surface of the first layer.
