Abstract
An organic light emitting diode (OLED) assembly (), comprising: a diode superstructure () comprising a cathode (), an anode () having a refractive index of na, and an organic light emitting semiconductor material () interposed between the cathode () and the anode (); and a light diffracting substructure () providing a scattering cross section of light from the diode superstructure (). The light diffracting substructure () comprises: a transparent substrate (), a plurality of nanoparticles () in contact with the substrate () and having a refractive index of n, and a planarization layer () over the nanoparticles () and having a refractive index of n. Further, nis within 25% of nand n>nIn addition, n> about 1.9.
