Abstract:
Described herein are elements for light emitting devices comprising: an emissive element comprising a host material and an emissive guest material and substantially free of light scattering material; and a light scattering element comprising either a non-emissive or an emissive material, wherein the light scattering element is between about 2.5% to about 60% by volume voids and the thickness ratio of light scattering element to the emissive element is at least 1 to about 2.
