Abstract:
1. A method of depositing an ink comprising an emissive material including a nanomaterial comprising quantum confined semiconductor nanocrystals that emit light having a predetermined wavelength, a material capable of transporting charge, and a liquid vehicle onto a layer of a light-emitting device, the method comprising: depositing the ink from a micro-dispenser onto the layer of the light-emitting device in a predetermined arrangement, wherein the layer comprises a second material capable of transporting charge and wherein the liquid vehicle included in the ink comprises an organic solvent in which the second material capable of transporting charge included in the layer is at least partially soluble, and wherein at least a portion of the nanomaterial and the material capable of transporting charge that are included in the ink is at least temporarily mixed in a portion of the second material capable of transporting charge that is soluble in the organic solvent.
