| titleOfInvention | Method for preparing OLED external light extraction layer with high light extraction efficiency of tungsten trioxide by ultrasonic spraying |
| abstract | The invention discloses a method for preparing an OLED outer light extraction layer with high light extraction efficiency of tungsten trioxide by ultrasonic spraying. Transport layer, light-emitting layer, electron transport layer, electron injection layer, cathode. In the preparation of the external light extraction layer by ultrasonic spraying of the present invention, firstly, a high-concentration precursor solution is obtained by dissolving the precursor ammonium paratungstate with a polar organic solvent with a large dipole moment and extremely volatile and dilute ammonia water, and then ultrasonically atomizing the precursor The solution passes through the organic phase filtrate transfer tube and the high-temperature transfer tube in turn, and the nozzle and the high-temperature transfer tube are used as the cathode and anode respectively to add pulse bias power to control the fluid velocity and spray uniformity, so that the fluid is sprayed on the glass substrate backplane to obtain the outer surface. light extraction layer. |
