1. A device comprising:
an inorganic emissive layer;
a first electrode layer; and
an outcoupling structure, and
a material disposed between the first electrode and the outcoupling structure,
wherein the first electrode layer is spaced from the inorganic emissive layer by a predetermined threshold distance that is a distance at which a total non-radiative decay rate constant is equal to a total radiative decay rate constant and wherein at least one of the first electrode, inorganic emissive layer, the outcoupling structure, or the material are corrugated.
