Abstract: |
This invention relates to an organic electroluminescent device. The device includes an anode layer, a cathode layer and a organic function layer which is located between the above two layers. At least one layer of organic function layer is doped with the doped materials which are selected from the lanthanide metal, the halide of lanthanide metal, the oxides of lanthanide metal or the carbonate of lanthanide metal. The lanthanide metal and its compounds can regulate the concentration of holes and electrons to make them to be more balance, and lanthanide metals and their compounds can significantly improve the stability of organic function layer to improve the life of OLEDs. |
