| Outline of Final Research Achievements |
A colloidal crystal, periodic array of colloidal particles, is a promising material that can be applied to various novel functional devices such as photonic crystals. However, there are some issues to be overcome for practical application, an impurity incorporation is one of critical problem. The detailed mechanism of impurity partitioning during colloidal crystallization has been revealed by using fluorescent particles in the present study. Orientation-dependent impurity partitioning and effect of grain boundary on partitioning was investigated quantitatively. These new findings significantly contribute to the control of impurity during colloidal crystallization.
