| titleOfInvention | A kind of red organic electroluminescence device and preparation method thereof |
| abstract | The invention provides a red organic electroluminescent device, comprising a substrate, an anode layer, an anode modification layer, a hole transport-electron blocking layer, a hole-dominated light-emitting layer, an electron-dominated light-emitting layer, a hole-blocker- Electron transport layer, cathode modification layer and cathode layer; the electron-dominated light-emitting layer includes: 0.05wt% to 2.0wt% organic sensitizing material, the organic sensitizing material is a transition metal complex with energy level matching; 1.0 Red organic luminescent material in wt%-8.0wt%; electronic organic host material in the rest. In the present invention, the electron-dominated light-emitting layer is doped with an organic sensitizing material, and the organic sensitizing material plays the role of a deep carrier binding center and an energy transfer ladder, which is beneficial to balance the distribution of carriers and broaden the The light-emitting region accelerates the energy transfer from the host material to the light-emitting material, thereby improving the efficiency of the device and reducing the operating voltage of the device. |
