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...

[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...

Abstract

The invention discloses a transparent optical multilayer film. The transparent optical multilayer film is composed of a substrate and a seed layer and is characterized in that the seed layer is formedthrough periodic overlapping of ZnO and PEDOT:PSS, Mg+ ions exist in the ZnO, and the transparent optical multilayer film is characterized in that the substrate is glass, PET, ITO and FTO. The transparent optical multilayer film is low in cost, high in repeating and suitable for large-area commercial producing and manufacturing, a solution component is easily regulated, the multilayer film photonstructure adopting PEDOT:PSS and MgZnO serves as the seed layer, the optical characteristic of the MgZnO thin film can be adjusted, and the electrical properties can be optimized.

Description

technical field [0001] The invention relates to a transparent optical multilayer film and a preparation method thereof, belonging to the technical field of photoelectric materials. Background technique [0002] As a new type of direct bandgap wide bandgap semiconductor material, it has excellent performance in many fields such as optoelectronics, piezoelectricity, pyroelectricity, and ferroelectricity. It has a wide range of uses, such as sensors, transparent conductive films, ultraviolet detectors, solar cells, and OLEDs, etc. [0003] In the application of optoelectronic devices, the poor conductivity of intrinsic ZnO affects the improvement of device performance. The commonly used method is to dope ZnO with metal ions such as Al3+, In3+, Ga3+, etc., which can significantly improve the conductivity of ZnO. However, the grain boundary scattering caused by excess carriers will cause the transmittance to decrease with the increase of doping amount. Contents of the inventi...
