Controlled assembly of colloidal clusters and its photonic properties |
초록 |
Icosahedral clusters are a new class of spherical colloidal crystals. However, the characterization of the icosahedral cluster has not been achieved. Here, we produce icosahedral clusters by slowly shrinking particle-laden water droplets in water-saturated oil. We controlled the drying time of aqueous droplets using a water-saturated hexadecane medium. In particular, we present real-time confocal measurement using dual dye labeling. The icosahedral clusters exhibit relatively strong structural colors compared to conventional onion-like supraballs. Moreover, the carbon-coated clusters further improve the saturation of structural colors. |
