胶体晶体是一种具有大规模制备潜力的光学三维光子晶体。我们发现，一个厘米大小的胶体晶体单晶域，一个有序的乳胶胶体阵列，可以通过一个动态过程瞬间定制，即，猝灭非平衡有序在浓悬浮液诱导的瞬时剪切流。在具有固定晶体取向的易处理容器中以极其简单的方式获得单晶，并且所得样品对于实际应用的外部干扰足够稳定。该方法将有助于光子晶体研究和应用的发展。
Colloidal crystals are potentially mass-fabricative and the most accessible three-dimensional photonic crystals in the optical regime. We found that a centimeter-sized single-crystalline domain of a colloidal crystal, an ordered latex colloidal array, could be instantaneously tailored through a dynamic process, i.e., quenching nonequilibrium ordering in a concentrated suspension induced by a momentary shear-flow. The single crystal is obtained in an extremely simple manner in a tractable container with a fixed crystallographic orientation, and resulting samples are sufficiently stable against external disturbance for practical application. The proposed method will contribute to the evolution of photonic crystal research and applications.
