Fabrication of Soft Photonic Crystal exhibiting Angle-independent Structural Color

我们首次证明了胶体颗粒的无定形阵列显示出与角度低相关的结构颜色。这一发现与人们普遍认为的周期性介电结构是光子带隙产生的基础相反。值得注意的是，所报道的具有这种光学现象的材料可以用作克服技术障碍的手段，在该技术障碍中，角度相关的结构颜色成为主要问题，例如在宽视角的全色显示器中。

We have demonstrated for the first time that an amorphous arrays of colloidal particles displays structural color with low-angle-dependence. This finding is in contrast to the common understanding that a periodic dielectric structure is fundamental to Photonic Band Gap production. It is worth noting that the reported material with such an optical phenomenon could serve as a means to overcome the technological barrier where angle-dependent structural color becomes a major issue, for example, in full color displays with wide viewing angles.
