specific Embodiment
[0019] The following is a specific embodiment of the present invention: a transparent optical multilayer film, which is composed of a substrate and a seed layer, and the seed layer is composed of periodically overlapping ZnO and PEDOT:PSS. The ZnO contains Mg ions.
[0020] Preferably: the substrate is glass, PET, ITO, FTO.
[0021] A method for preparing a transparent optical multilayer film mainly includes the following steps:
[0022] a. Prepare the ZnO seed layer precursor solution: Dissolve an appropriate amount of zinc acetate in ethylene glycol methyl ether, heat and stir on a 40-60 degree hot plate with a magnetic stirrer until the zinc acetate is completely dissolved, and drop in the stabilizer ethanolamine, Continue to stir until clarified, age for 24 hours or more, and set aside;
[0023] b. Prepare ZnO seed layer growth solution: Weigh an appropriate amount of zinc nitrate hexahydrate and hexamethylenetetramine (HMT), and the molar ratio of the two is 1:1, then m...
Embodiment 1
[0031] Weigh 1.97g of zinc acetate and 0.21g of magnesium acetate, dissolve the drug in 50 mL of ethanol, heat and stir on a magnetic stirrer (at a temperature of 50°C) for 15 min; then add 0.54 mL of stabilizer monoethanolamine dropwise to the above In the solution (after 30 seconds of dripping), stirring was continued at 50°C for 30 minutes until the solution was clear, and the MgZnO seed layer precursor was obtained.
[0032] The glass substrate was ultrasonically cleaned with isopropanol, a washing solution with a volume ratio of H2O:HCl = 2:1, absolute ethanol, and deionized water for 10 min, and then dried in an oven for later use. The MgZnO seed layer precursor solution was spin-coated on the cleaned glass substrate at a rotation speed of 2000 rpm for 20 s. Then place the glass substrate carrying the MgZnO seed layer precursor solution on a hot plate for rapid temperature rise annealing treatment. The rapid temperature rise annealing method is as follows: the temperatur...
