A school badge based on scalable structural color — •Shiyao Jia, Yudie Huang, Yi Wang, Wenxin Wang, Zhihang Wang, Jiaxu Chen, and Fanzhou Lv — Harbin Engineering Unversity,Harbin,China

The researches on alumina membrane already has hundreds of years, and owing to its highly ordered honeycomb structure, anti-corrosion, transparencyand mechanical properties, the alumina membrane has become a hot spot in nanotechnology in these years. Here, the optical interference at the interfaces of alumina membrane is used to selectively reflect the light and present the structural color, based on this theory, we made a vivid and colorful school badge. The thickness of alumina membranes are regulated by controlling the anodizing conditions precisely. Different light with specific frequency can be reflected by changing the thickness of alumina membranes, thus demonstrating the relevant structural color on corresponding areas and presenting the picture of school badge, which can be further developed as a nanophotonic device for sensing.
