specific Embodiment approach 1

[0017] Specific embodiment one: the present invention utilizes magnetron sputtering method to prepare the method for double-layer nickel oxide electrochromic thin film is to realize according to the following steps:

[0018] 1. Ultrasonic clean the glass substrate covered with ITO in trichlorethylene, acetone, and ethanol for 5-10 minutes to remove the dust and grease covered on the surface, and then use deionized water to clean the substrate to remove the residual ethanol , and finally blow dry with nitrogen to obtain a clean ITO substrate.

[0019] 2. The present invention adopts radio frequency reaction co-sputtering method to prepare crystalline nickel oxide film, and the target material used is metallic nickel with a purity of 99.99%. Use the clean ITO substrate obtained in the previous step as the substrate. First vacuumize the vacuum chamber, when the pressure in the chamber reaches 4×10 -4 When Pa is below, turn on the heater to heat the substrate, and start to fill ...

specific Embodiment approach 2

[0021] Embodiment 2: This embodiment is different from Embodiment 1 in that: the ITO glass described in step 1 is replaced by FTO glass. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0022] Embodiment 3: This embodiment is different from Embodiment 1 or Embodiment 2 in that the temperature of the substrate during pre-growth is 200°C-400°C. Others are the same as in the first or second embodiment.

Abstract

The invention discloses a preparation method of a vanadium-doped double-layer nickel oxide electrochromic film. The ratio of doped vanadium ions can be effectively controlled by controlling the sputtering power ratio of a vanadium target and a nickel target. NiO deposited in the lower layer of the film belongs to a crystalline state, crystal lattices of the film are closely arranged, the degree oforder is good, and the film is uneasy to degrade in the circulating process, therefore, the stability of the film with the structure in the circulating process is guaranteed. In conclusion, a synergistic effect between a crystalline film and the doped film can enable the electrochromic performance of the nickel oxide film to be obviously improved. The preparation method of the vanadium-doped double-layer nickel oxide electrochromic film is simple and convenient to operate, is easy to promote and plays very positive significance in commercial promotion of the NiO electrochromic film.

Description

technical field [0001] The invention relates to a method for preparing a vanadium-doped double-layer nickel oxide electrochromic film. Background technique [0002] Electrochromism is a kind of optical performance changeable discoloration, which generally refers to the reversible color change of materials under the action of external electric field or current, which is intuitively manifested as the process of reversible changes in the color and transparency of materials, which is continuously adjustable of. Traditional agricultural greenhouses can be roughly divided into the following three types: glass greenhouses, solar panel greenhouses and film greenhouses. This kind of greenhouse can only adjust the energy entering the greenhouse and escaping from the greenhouse by artificially covering the film or laying carpets. This kind of adjustment method is relatively primitive, and the energy cannot be adjusted linearly. Electrochromic modification of the constituent materials...
