[0022] See figure 1 .
[0023] (1) Preparation of sol: Weigh 2.2g zinc acetate into a 50mL conical flask, add 19.4mL ethylene glycol monomethyl ether and 0.6mL ethanolamine, stir and heat in a water bath at 70°C for 1 hour, then transfer to the conical flask Add 0.1149g of yttrium nitrate (doping amount of 3.0%), continue heating and stirring for 2 hours to obtain a transparent and clear sol, which will be used after cooling to room temperature;
[0024] (2) Cleaning of glass substrate: use detergent and 3mol / L H 2 SO 4 Solution, 1mol / L NaOH solution, deionized water, acetone, absolute ethanol ultrasonic cleaning;
[0025] (3) Preparation of the film: the sol obtained in step (1) is applied to the glass substrate cleaned in step (2) by spin coating; then the glass substrate coated with the sol is dried on a heating plate at 80°C After 10 minutes, place it in a muffle furnace at 450°C for 2 minutes to anneal, and repeat the above sol coating, drying and annealing te...
