Claim 16:
17. A method for fabricating a light-emitting device comprising:
preparing a substrate;
forming a first electrode on the substrate;
depositing a first layer deposited on the first electrode, the first layer comprising a first material capable of transporting holes;
forming an emissive layer on the first layer by depositing an ink composition comprising a nanomaterial and a non-polar organic solvent liquid vehicle,
depositing a second layer on the emissive layer, wherein the second layer the comprises a second material capable of transporting electrons; and
forming a second electrode deposited on the second layer,
wherein the nanomaterial comprises a plurality of quantum confined semiconductor nanocrystals, and
wherein the nanomaterial has a solubility less than 0.001 milligrams per milliliter in the non-polar organic solvent liquid vehicle.
