摘要：
Reflected light from the display can seriously affect the quality of the display image. In addition, most of the light from the laser pointer passes directly through the display when it hits it, making it difficult to see the laser pointer's light spot. In this paper, ZnO quantum dots as photoluminescent materials were added into SiO2 sol to form a composite coating with photoluminescent and anti-reflective double properties. The composite coating can reduce the reflected light of display substrate from 11.4 % to 4.2 % in 400 similar to 780 nm band without annealing treatment. In addition, ZnO quantum dots absorb light up to 400 nm and emit visible light from 500 to 700 nm. When the 365 nm laser pointer illuminates a specific area of the sample, a bright yellow dot appears in that area.
