CRYSTALLIZATION OF COLLOIDAL CRYSTAL AND SYNTHESIS OF THREE- DIMENSIONAL PERIODIC LATTICE CLUSTER MATERIALS

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 crystallization of colloidal crystals and the synthesis of three\|dimensional periodic lattice cluster materials based on colloidal crystal are of great interest in experimental condensed matter physics.An introduction is given to the physical mechanism of ordering of colloidal particles in aqueous suspension,their structural phase transitions,the formation of morphologies,and the synthesis of three\|dimensional periodic lattice cluster materials based on colloidal crystal.There is still not enough experimental evidence or theoretical explanation for the physical mechanism of ordering by self\|organization that occurs in colloidal suspensions.Colloidal crystals open up a new way of designing such three\|dimensional lattice materials with novel functions which may have important potential applications in photonics and other fields.
