摘要: 光子晶体是一种具有光子带隙的新型功能材料.利用胶体粒子自组装三维光子晶体由于其制备过程比较经济、简单,从而为很多人所关注.目前报道的方法已有多种.其中垂直排列法的简便易行使得其受到了广泛的研究,但另一方面这种方法本身的缺点也限制了它的使用范围.针对这种情况,很多研究机构提出了他们的改进方法.本文简要概述了在这一方面的最新进展,并且在本实验室已能够制备任意单分散、均一尺寸二氧化硅粒子的基础上,采用恒温快速蒸发自组装法得到了高质量的胶体晶体排列.

Abstract: Self-assembling growth of spherical colloidal particles is a promising technique to fabricate photonic crystals. Compared to other self-assembly methods, the vertical deposition method has received considerable attentions. We reviewed the recent developments of the improved vertical deposition methods. By using isothermal heating evaporation-induced self-assembly method, silica spheres with different diameters, which can be obtained with well-defined sizes and a very narrow size distribution in our laboratory, were self-assembled into superior quality colloidal crystals.

Key words: photonic crystals, colloidal crystals, self-assemble, vertical deposition, monodispersed silica sphere
