| titleOfInvention | A kind of blue organic electroluminescence device and preparation method thereof |
| abstract | The invention provides a blue 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, and a hole-blocking layer arranged in sequence. ‑Electron transport layer, cathode modification layer and cathode layer; the electron-dominated light-emitting layer includes the following components: 0.05wt% to 2.0wt% organic sensitizing material, the organic sensitizing material is a transition metal with energy level matching Complex; 8.0wt%-25.0wt% of blue organic luminescent material; the rest of electronic organic host material. In the present invention, the organic sensitizing material can act as a carrier deep binding center and an energy transfer ladder, which is beneficial to balance the distribution of carriers, broaden the light-emitting range of the device, and accelerate the transition from the host material to the light-emitting material. energy transfer, thereby reducing the operating voltage of the light emitting device and improving the efficiency and color purity of the light emitting device. |
