Summary:Several iridium-based complexes were investigated as phosphorescent dopants. They achieved about 100% internal quantum eciency,duetoutilizationofbothsingletandtripletexcitonsintheradiativeprocesses.WehavefabricatedphosphorescentOLEDswith8%Ir(ppz)3as a triplet emissive dopant in various host materials. CBP, which has an eciency of 0.20 cd/A, is the best host material. Furthermore, wesynthesized metal-organic phosphor complexes based on Ir with dierent ligands as to (Im)2Ir(acac), (Im-R)2Ir(acac), and Ir(ppz)2(acac). KCI Citation Count: 16
