摘要:
Disclosed are an organic electroluminescent device having ternary doped hole transportation layer and a preparation method therefor. The electroluminescent device comprises a conductive anode substrate (1), a ternary doped hole transportation layer (2), a light-emitting layer (3), an electron transportation layer (4), an electron injecting layer (5) and a cathode layer (6), wherein the material for the ternary doped hole transportation layer (2) is a mixed material made by doping a cerium salt and a hole transportation material into a metal compound. The electroluminescent device forms p-doping by doping the cerium salt and the hold transportation material into the metal compound, which improves the ability of injecting and transporting holes, and increases the efficiency of light emission. Since the material for the ternary doped hole transportation layer (2) is predominately a metal compound, the process difficulty and manufacturing costs are reduced, facilitating industrial production and commercial applications.
