| titleOfInvention | White-light luminescent part and preparation method thereof and white-light electroluminescent device |
| abstract | The invention is applicable to the technical field of electroluminescence, and provides a white-light luminescent part and a preparation method thereof and a white-light electroluminescent device. The white-light luminescent part comprises a first blue-light luminescent layer, a second blue-light luminescent layer and a red-light and green-light mixed luminescent layer between the first blue-light luminescent layer and the second blue-light luminescent layer, wherein the three luminescent layers are stacked, and the first blue-light luminescent layer and the second blue-light luminescent layer are made of mixture of blue-light phosphorescent materials and hole transmission materials with the energy gap higher than 3.5ev. By means of the hole transmission materials with the ultra-wide energy gaps, energy loss during energy transmission is avoided, and luminescence efficiency is greatly improved; the first blue-light luminescent layer and the second blue-light luminescent layer form a quantum trap structure, and luminescence of the red-light and green-light mixed luminescent layer can be stabilized; and the preparation method is simple in operation, low in cost, high in production effectiveness and extremely suitable for industrial production. |
