摘要
胶体晶体是指由分散的微米级或亚微米级的胶体颗粒形成的具有有序结构的一类物质。自组装技术是胶体晶体制备工艺中一种常用的方法。概述了胶体晶体的基本概念及自组装的相关工艺,针对其在微纳光学领域的应用展开了详细的分析,介绍了不同的研究团队如何将自组装胶体晶体用于彩色打印、全息图、抗反射涂层、光学器件制造中,并对胶体晶体发挥的作用进行了归纳总结。胶体晶体独特的周期性结构赋予了它广阔的应用前景,通过不同的自组装技术提升胶体晶体的质量具有重要的意义。
Colloidal crystals are materials that exhibit an ordered structure formed by dispersed micron or submicron colloidal particles.The self-assembly technology is a commonly used method to manufacture colloidal crystals.The basic concepts of colloidal crystals and the related self-assembly processes are outlined in this review.Furthermore,the applications of self-assembled colloidal crystals in case of micro-nano optics are presented in detail.Subsequently,other applications of self-assembled colloidal crystals,such as color printing,holograms,antireflective coatings,and optical devices,are presented and the roles of colloidal crystals in those applications are summarized.The unique periodic structure of colloidal crystals ensures its broad application prospects.Therefore,improving the quality of colloidal crystals using various self-assembly techniques is of considerable importance.
