我们讨论了直径为几百纳米的有机和无机单分散胶体，分别描述了乳液聚合和斯托伯技术用于生产有机和无机颗粒的方法。讨论了这类粒子的有序层在光子学中的应用，特别提到了光子带隙的获得，并简要回顾了这一问题的理论处理。下面回顾了用来形成这些材料良好有序多层的主要方法。描述了用另一种化合物填充这些多层的间隙，然后蚀刻出原始粒子的所谓反向结构。给出了原始多层和反向多层的一些较重要的光学研究结果。
We discuss both organic and inorganic monodispersive colloids having diameters of the order of a few hundred nm. The use of emulsion polymerisation and the Stober technique to produce organic and inorganic particles respectively is described. The application of ordered layers of such particles in photonics is discussed with particular reference to obtaining a photonic bandgap and the theoretical treatments of this question are briefly reviewed. There follows a review of the principal methods which have been employed to form good ordered multilayers of these materials. The so called inverted structures made by filling the interstices of these multilayers with another compound and then etching out the original particles are described. The results of some of the more important optical studies of both original multilayers and inverted multilayers are given.
