Problems solved by technology

[0003] But as of now, the preparation of ZnO or TiO 2 Thin films mainly adopt physical preparation processes such as magnetron sputtering and pulsed laser deposition. The above preparation processes are complex, the preparation temperature is high, and the size of the film is limited, and the cost cannot be effectively controlled in large-scale industrial production. At the same time, the above preparation processes There are certain requirements on the substrate, and the production of flexible devices cannot be realized
