    • An organic electroluminescent device and a conductive substrate thereof are provided. Said conductive substrate includes a glass substrate, an indium tin oxide (ITO) layer and a metal oxide layer located between said glass substrate and said ITO layer. The refractive index of said metal oxide layer ranges between that of said glass substrate and said ITO layer. Due to the metal oxide layer, the refractive index of which ranges between that of the glass substrate and the ITO layer, is inserted into said conductive substrate, when the light extracts between the ITO/metal oxide layer and the metal oxide layer/glass, the critical angle of total reflection increases compared with that without the inserted metal oxide layer. Most part of light extracts out of the interface after refraction, and only small part of light is totally reflected, thus the light extraction enhances.

    • An organic electroluminescence device comprises the following structure: a conductive base (110), a hole injection layer (120), a light emission layer (140), and a cathode layer (170) are laminated in sequence. The material of the hole injection layer (120) comprises a conductive polymer and an azo initiator. A nano-network structure is provided on the connecting surface of the hole injection layer (120) and the light emission layer (140). After being heated to a higher temperature, the azo initiator can be decompounded to release N2, thus the nano-network structure is formed on the surface of the hole injection layer (120). The nano-network structure can efficiently increase the contacting area of the hole injection layer (120) and the adjacent layer. The injection efficiency of the hole is improved. A manufacturing method of the organic electroluminescence device is also provided.

    • 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.
