We report phosphorescent organic light-emitting diodes with a substantially improved light outcoupling efficiency and a wider angular distribution through applying a layer of zinc oxide periodic nanopillar arrays by pattern replication in non-wetting templates technique. The devices exhibited the peak emission intensity at an emission angle of 40 degrees compared to 0 degrees for reference device using bare ITO-glass. The best device showed a peak luminance efficiency of 95.5 +/- 1.5 cd/ A at 0 degrees emission (external quantum efficiency-EQE of 38.5 +/- 0.1%, power efficiency of 127 +/- 1lm/W), compared to that of the reference device, which has a peak luminance efficiency of 68.0 +/- 1.4 cd/ A (EQE of 22.0 +/- 0.1%, power efficiency of 7261 lm/W).
