1. An electroluminescent device comprising:
a substrate;
a first electrode disposed on the substrate;
an emission layer comprising luminescent nanostructures disposed on the first electrode;
a hybrid transport layer disposed on the emission layer, wherein the hybrid transport layer comprises an organic layer and inorganic nanostructures disposed within the organic layer, wherein the luminescent nanostructures are separated from the inorganic nanostructures by the organic layer, and wherein the organic layer and the luminescent nanostructures do not react chemically with each other; and
a second electrode disposed on the hybrid transport layer.
