[0018] First put the substrate into acetone, clean it with ultrasonic wave for 15 minutes, then put the substrate into absolute ethanol, clean it with ultrasonic wave for 15 minutes, then put the substrate into deionized water and clean it with ultrasonic wave for 15 minutes, and finally put the substrate into the oven Dry in medium. Weigh 0.6972g of zinc acetate solid and 8.67768g of thiourea solid, add to 300ml of deionized water and dissolve to obtain a mixed solution containing 0.01mol / L zinc ion and 0.3mol / L sulfide ion. Add 60ml of Triton solution with a concentration of 5mmol / L into the beaker containing the mixed solution, and heat it in a constant temperature water bath at 70°C. When the temperature of the solution in the beaker reaches 60°C, insert the substrate into the polytetrafluoroethylene frame and immerse it into the beaker, and add 20ml of ammonia solution with a concentration of 14.82mol / L to the mixed solution in the beaker, and finally cover the mouth of t...
