Problems solved by technology

[0013] Although the sol-gel process can uniformly form a large area of ​​film, the thickness of the film is directly related to the viscosity of the precursor solution and the rate of pulling or spin coating, which is difficult to control accurately, and the front and rear ends of the film prepared by the pulling method or The thickness of the central area and the outer edge of the film prepared by the spin coating method also has a certain difference, which affects the high uniformity of the performance
