3D nanostructures have received great attention in many fields because of their mechanical strength, regular porosity, and optical properties. For example, 3D nanostructures can be used as scaffolds for energy devices such as electrode and membrane. Although the regular arrays have advantages for optical devices which need a low transmittance or high reflectance, conventional fabrication method of 3D nanostructure has limitation on fabrication cost and diversity of their shape. In this study, we report a simple and cost-effective method that can generate hierarchical 3D nanostructures in large areas. For producing the interference pattern of light, we used monodisperse colloidal particles as phase elements. By combining the near-field interference of light and photocurable polymer, we can fabricate regular 3D nanostructures. To control the lattice constant of 3D nanostructures, we investigated effect of UV exposure times and colloidal particle size on that of 3D nanostructures. |
