An OLED may include regions of a material having a refractive index less than that of the substrate, or of the organic region, allowing for emitted light in a waveguide mode to be extracted into air. These regions can be placed adjacent to the emissive regions of an OLED in a direction parallel to the electrodes. The substrate may also be given a nonstandard shape to further improve the conversion of waveguide mode and/or glass mode light to air mode. The outcoupling efficiency of such a device may be up to two to three times the efficiency of a standard OLED. Methods for fabricating such a transparent or top-emitting OLED is also provided.

OLED with improved light outcoupling

Certain iridium compounds which may comprise an iridium(III)-ligand complex having the general formula: (C^N)&#x2014;Ir&#x2014;(N^N). (C^N) and (N^N) may each represent a ligand coordinated to an iridium atom. The iridium compounds may have a primary phosphorescent photoluminescence peak wavelength in the near-infrared (IR) range. Also, organic devices that use certain iridium compounds. The organic device may comprise an organic layer and the organic layer may comprise any of the iridium compounds disclosed herein. Also, organic devices that use certain metalloporphyrin compounds. The metalloporphyrin compounds may comprise a core porphyrin structure with four pyrrole rings. The metalloporphyrin compounds may have a primary phosphorescent photoluminescence peak wavelength in the near-IR range.
