Outline of Final Research Achievements

Light is reflected at the interface between different refractive index materials. The reflectance depends on the difference of the refractive indices. For example, 4% of light is reflected at one-side of a commercially available transparent glass. In this study, we researched micro-refractive structural formation on/in the glass for antireflection. Generally, it is not easy to fabricate the microstructure to glass because of its high hardness and softening temperature. Our proposed technique using corona discharge selective deposition successfully formed the SiO2 microstructure onto the soda-lime silicate glass under the experimental condition below 200 °C without vacuum equipment and corrosive gas. Furthermore, the reflectance from the glass with refractive microstructure was simulated by rigorous coupled wave analysis.
