中文摘要：

光子晶体是一种介电常数（或折射率）可以周期性调制的结构，其自激辐射抑制和光子局域化性质使其可以简便而有效地限制、控制和调控光子。近年来，利用胶体晶体自组装性质与水凝胶的传统应用相结合制成的凝胶光子晶体在药物释放、光学开关、金属探针、生物传感器等新应用方面的研究蓬勃发展，在新材料开发及临床应用等方面取得巨大进展。本文概述了胶体晶体自组装并对该类凝胶光子晶体进行了分类介绍，对其发展趋势也进行了评述和展望。

英文摘要：

Photonic crystal is one type of materials in which the permittivity （or refractive index）changes periodically. The stimulated radiation inhibition and localization of this material make it confine, dominate and modulate the photos effectively. During the last decade, the photonic crystal in hydrogel self-assembly of the colloidal crystal and the environmental responsive property （PCH）, of the h which holds both the virtues of ydrogel , plays a more and more important role in new applications such as drug delivery, optical switches, ion optrode, biosensors and so on. A summarization of the self-assembly of the colloidal crystalline and a classified introduction, as well as the developing trend of the photonic crystal in hydrogel are proposed in this paper.
