Phosphorescent oriented emitters can significantly increase the efficiency of organic light‐emitting diodes (OLEDs). Recent studies have shown that there exist non‐isotropically oriented emitting guest/host systems based on small molecules. We have developed a method for determining the emitter orientation and its influence for efficiency analysis of state‐of‐the‐art OLEDs.
