| titleOfInvention | Organic light-emitting device and preparation method thereof |
| abstract | The invention provides an organic light-emitting device comprising a conductive anode substrate, a hole injection layer, a hole transport layer, a luminescent layer, an electron transport layer, an electron injection layer and a composite cathode layer. The above-mentioned layers are successively laminated. The composite electrode includes a first doping layer, a metal layer, and a second doping layer, wherein the layers are successively laminated. The first doping layer is made of a mixing material formed by a metallic oxide and a metal material with the work function of -2.0eV to -3.5eV, wherein the metallic oxide can be titanium dioxide, zinc oxide, magnesium oxide or zirconium oxide; the metal layer is made of silver, aluminum, platinum or gold; and the second doping material is made of a mixing material formed by metal sulfide and the metal material, wherein the metal sulfide can be zinc sulfide, cadmium sulfide, magnesium sulfide or copper sulphide. Because of the composite cathode layer, the light can be scattered and then be emitted to the bottom of the device, thereby improving the luminous efficiency of the device. In addition, the invention also provides a preparation method of the organic light-emitting device. |
