Embodiment 1
[0019] Preparation system: Magnetron sputtering preparation technology is adopted. The magnetron sputtering system consists of a transition chamber and a main sputtering chamber (45 cm in diameter). The main sputtering chamber is connected with a molecular diffusion pump, and the ultimate vacuum is 2.0×10 -6 Pa. The sputtering chamber has three target positions for three different 2-inch diameter targets. Each target position is inclined upward at an angle of 30°, and can be co-sputtered upwards in a confocal manner or sputtered upwards in a three-target independent manner. The sample stage can be heated up to over 600°C and can keep rotating continuously during the sputtering process.
[0020] Substrate treatment: In the experiment, the substrate was made of float glass. The substrate was ultrasonically cleaned in anhydrous alcohol and acetone for 5 minutes successively, after drying, it was fixed on the sample carrier and placed in a transitional vacuum chamber for vacuu...
Embodiment 2
[0026] The preparation system, substrate treatment, and preparation methods are the same as in Example 1.
[0027] Preparation conditions: TiO 2 The preparation conditions were exactly the same as in Example 1, and the sputtering power of Ag was increased to 12W to increase the loading of Ag nanoparticles in the film layer (about 22%).
[0028] The thus prepared coated glass exhibits a light purple color. After the glass is exposed to sunlight, the film surface has good hydrophilicity.
Embodiment 3
[0030] The preparation system, substrate treatment, and preparation methods are the same as in Example 1.
[0031] Preparation conditions: TiO 2 The preparation conditions were exactly the same as in Example 1, and the sputtering power of Ag was increased to 18W, which further increased the loading of Ag nanoparticles in the film layer (about 43%). The diameters of Ag nanoparticles are mainly distributed between 70 and 160 nm, and they are uniformly distributed in TiO 2 In the film
[0032] The thus-prepared coated glass exhibits a purplish red color. After the glass is exposed to sunlight, the film surface has good hydrophilicity.
