Claim:
1. A light emitting device comprising: a first charge transporting layer including a first inorganic material in contact with a first electrode arranged to introduce charge in the first charge transporting layer, wherein the first inorganic material is amorphous or polycrystalline; a second electrode; a layer including an emissive material comprising a plurality of semiconductor nanocrystals disposed between the first electrode and the second electrode, and a doped layer proximal to the nanocrystals, wherein the doped layer includes a dopant comprising an oxygen deficiency, a halogen dopant, a mixed metal, a p-type dopant, or an n-type dopant in an amount effective to minimize non-radiative losses; wherein the band gap of the first inorganic material is greater than the emission energy of the semiconductor nanocrystals.
