Abstract
Light-emitting devices and methods of making the same are described whereby lenses of any array include a material with a higher refractive index than an encapsulation layer of a substrate layer, the refractive index of the material being in a range of greater than 1.7 to 1.9 at 400 nm. The material forming the lenses includes nanocomposite comprised of inorganic nanocrystals and a polymeric matrix, wherein the nanocrystals are selected from the group consisting of ZrO, ZnO, MgO, HfO, NbO, TaOand YO. A 3-4 micron thick sample of the nanocomposite has an optical transmittance of at least 80% over a range of 440 nm to 800 nm.
