43.4: Invited Paper : Non‐isotropic Emitter Orientation in Organic Light‐emitting Diodes

Abstract 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.
