胶体晶体结晶的物理过程和以胶体晶体为基的三维周期性集团点阵材料的制备是目前实验凝聚态物理的一个热点领域 .文章对胶体颗粒在悬浮液中自组织有序化的物理机制、结构相变与形态的形成和以胶体晶体为基的人造三维周期性点阵材料作了介绍 .无论是从实验上还是理论上来看 ,对胶体体系中发生的自组织有序化的物理机制还没有给出令人信服的证据和解释 .而胶体晶体的制备为具有新异功能的三维周期性集团点阵材料设计开辟了一条新途径 ,因而在光子学和其他领域具有重要的应用价值 .
The physical process of colloidal crystal crystallization and the preparation of three-dimensional periodic group lattice materials based on colloidal crystals are currently a hot area of experimental condensed matter physics.In this paper, the physical mechanism of colloidal particles self-organized and ordered in suspension, Structure phase transition and morphological formation and colloid-based artificial three-dimensional periodic lattice materials are introduced.No matter from the experimental or theoretical point of view, the colloidal system occurs in the organization of self-organized physical mechanism No convincing evidence and explanations have been given yet.The preparation of colloidal crystals opens up a new way for the design of novel three-dimensional periodic groups of lattice materials with novel functions and therefore has important applications in photonics and other fields.
