HIGHLY STABLE AND EFFICIENT OLEDS WITH A PHOSPHORESCENT-DOPED MIXED LAYER ARCHITECTURE
摘要
A highly stable and efficient organic light emitting device with a phosphorescent-doped mixed layer architecture comprises an anode layer; hole injecting layer over the anode layer; a mixed layer over the hole injecting layer, the mixed layer comprising an organic small molecule hole transporting material, an organic small molecule electron transporting material and a phosphorescent dopant; and a cathode layer over the mixed layer. An electron transporting layer may be present between the mixed layer and the cathode layer and a hole transporting layer may be present between the hole injecting layer and the mixed layer.
