Embodiment 2
[0037] It is basically the same as Example 1, except that:
[0038] The first antireflection layer 45 is a silicon nitride layer with a thickness of 10-20 nm;
[0039] The second antireflection layer 46 is a PEG-doped silica-titania composite layer with a thickness of 30-40nm; the content of the PEG in the silica-titania is 5%; the quality of the silica and titania The ratio is 1:1;
[0040] Both the first antireflection layer 45 and the second antireflection layer 46 have two layers.
[0041] The transition layer 47 is a titanium dioxide layer including a low-concentration self-cleaning agent, with a thickness of 10-20 nm; the mass percentage of the self-cleaning agent in the titanium dioxide composite layer is 1%;
[0042] The medium-efficiency self-cleaning and antireflection layer 48 is a silica-titania composite layer including a medium-concentration self-cleaning agent, and its thickness is 20-30 nm; the quality of the self-cleaning agent in the silica-titania composite layer is ...
