| titleOfInvention | A kind of white light organic electroluminescence device and its preparation method |
| abstract | The invention discloses a white light organic electroluminescence device and a preparation method thereof, belonging to the technical field of organic electroluminescence, and the specific steps include: (1) cleaning an ITO substrate; (2) adopting a spin coating process On the ITO substrate, the hole transport layer is spin-coated; (3), the ITO substrate of step (2) is placed on an inclined plane, and the organic solution is sprayed on the hole transport layer to form a luminescent layer; (4) using a vacuum The thermal evaporation process vapor-deposits an electron transport layer, a cathode modification layer and a cathode layer sequentially on the substrate in step (3). The invention adopts the slope method to introduce gravity to remove excess solution in the liquid film, and forms a uniform liquid film on the substrate under the action of intermolecular force and surface force, avoiding the influence of complex solution flow behavior and further eliminating the problems caused by ultrasonic spraying of organic films. The existing folds realize a multi-component organic thin film with a flat surface, and use it as a light-emitting functional layer to prepare a single-layer white light organic electroluminescent device with uniform white light emission and high efficiency. |
