由氧化铁磁性球组成的胶体光子晶体（CPhCs）具有高的晶格可调谐性，但通常不稳定并且难以以液体形式管理。我们通过将胶体球引入树脂系统来解决这个问题，该树脂系统可以通过光聚合来“冻结”三维（3D）图案。因此，实现了具有各种结构颜色的坚固的固体形式CPhCs。“冻结”的3D图案不仅允许对自组装动力学，胶体晶体学和PhC物理学进行系统的探索，而且还可以为固体但仍然柔软的PhC成形或切片铺平新的应用途径。
Colloidal photonic crystals (CPhCs) consisting of iron oxide magnetic spheres possess high lattice tunability but are generally unstable and difficult to manage in liquid form. We solve the problem by introducing the colloidal spheres into a resin system, which can “freeze” three-dimensional (3D) patterns by photopolymerization. Robust solid-form CPhCs with various structural colors were, therefore, achieved. The “frozen” 3D patterns would permit not only a systematic exploration on self-assembling dynamics, colloidal crystallography, and PhC physics but also may pave a new application avenue if a solid, but still soft, PhC is shaped or sliced.
