Abstract:Imitation and learning are the eternal topics for human beings to ask for knowledge from nature. The absorption of light by the nanometer scale structure covered by the moth's eye surface has inspired people's thinking about the role of sub-wavelength structure and light. Anti-reflection technology reduces the loss of light energy during propagation. This technology is widely used in optical system, solar cells, optoelectronics devices, display screens, window components and so on. The concept of moth eye anti-reflection micro-nano structure surface provides a new idea and opportunity for the development of optical anti-reflection technology. This review briefly reviews the basic concept of the moth eye anti-reflection structure surface technology and the development of this technology, and summarizes the various processing techniques applied to the surface of anti-reflective micro-nano structure. Some new technological development directions have also been discussed. It is hoped to provide useful research ideas for scholars and technicians engaged in anti-reflective technology research.
