摘　　要：光子晶体是由不同折射率材料周期性排列而成的结构,由于其独特的光学性质及优异的色彩饱和度,已经成为结构色材料中最重要的类型.过去几十年来,纳米粒子自组装制备光子晶体具有精准、成本低以及易大面积等优势,已经得到了广泛的研究和关注.综述了近期光子晶体结构色材料的研究进展,包括其基本的生色机制,制备方法以及在显示、色度传感和信息防伪加密等方面的实际应用.其中重点讨论了“自下而上”自组装的制备方式,并且强调了图案化和大面积结构色材料的制备方法.最后,对目前自组装制备光子晶体结构色材料所面临的挑战以及未来发展的方向进行了展望.Photonics crystals are structures composed of materials with different refractive indices arranged periodically.Due to their unique optical properties and excellent color saturation,they have become the most important type of structural color materials.In the past few decades,the fabrication of photonic crystals using self-assembly of nanoparticles has attracted widespread research attention due to its precision,low cost,and ease of large-scale production.The recent research progress on photonic crystal structural color materials,including their basic color production mechanisms,fabrication methods,and practical applications in displays,color sensing,and information anti-counterfeiting encryption is reviewed with focuses on the fabrication of photonic crystal structural colors using a“bottom-up”self-assembly approach.And the methods for producing photonic crystal patterns and large-area structural color films are emphasized.Finally,the challenges faced by current self-assembly fabrication of photonic crystal structural color materials and prospects for future development directions are discussed.
