Spin‐coated small‐molecule organic light‐emitting diodes (OLEDs) based on green‐emitting Ir(mppy) 3 ‐doped 4,4'‐bis(9‐carbazolyl)‐biphenyl (CBP) blended with electron‐ and hole‐transporting molecules are demonstrated to have very high efficiencies (up to 60 lm/W and 69 Cd/A without any outcoupling enhancement, which can double with a high‐quality microlens array). An additional electron‐transporting/hole‐blocking BPhen layer is thermally evaporated on the active layer, followed by the LiF/Al cathode.
