| titleOfInvention | Core-shell material for electron transmission, preparation method thereof and electroluminescent device |
| abstract | The invention relates to a core-shell material for electron transmission, a preparation method thereof and an electroluminescent device. The core-shell material for electron transmission comprises a first metal oxide core body and a second metal oxide shell layer coated on the surface of the first metal oxide core body; the first metal oxide has a metal-oxygen bond energy that is less than the metal-oxygen bond energy of the second metal oxide. The surface of the first metal oxide nucleus body is coated with the second metal oxide shell layer, so that the effect of passivating the surface of the first metal oxide nucleus body is achieved, the electron mobility and the electron concentration of the first metal oxide nucleus body are reduced, the second metal oxide shell layer can be used as an electron transmission material and can be applied to an electroluminescent device, the fluorescence characteristic of a light emitting layer is guaranteed, and the efficiency of the electroluminescent device is improved; furthermore, the life of the electroluminescent device is more gradually shown, and the forward aging is alleviated. |
