| titleOfInvention | A kind of nanometer material and its preparation method and quantum dot light-emitting diode |
| abstract | The invention discloses a nano material and a preparation method thereof and a quantum dot light emitting diode. The preparation method of the nanomaterial includes the steps of: reacting metal salt, cobalt salt, nickel salt and alkali solution to obtain a nanomaterial including metal oxide and cobalt element and nickel element doped in the metal oxide. In the invention, two transition metals, cobalt and nickel, are used to dope the metal oxide, so as to adjust the transmittance and electron transport performance of the film layer after the metal oxide is formed into a film. Cobalt doping will improve the flatness and crystallinity of the film surface, so that the scattering effect of the film layer is weakened, that is, the transmittance of the film layer is enhanced. The doping of nickel can reduce the resistance of the film, thereby improving the electron transport performance of the film. In the present invention, the respective advantages of cobalt and nickel are selected, and two transition metals of cobalt and nickel are used to co-dope the metal oxide, so as to simultaneously improve the transmittance and electron transmission performance of the film layer after the metal oxide is formed into a film, so as to improve the device. performance purpose. |
