On evaporation of water in polystyrene colloidal emulsion, the polystyrene colloidal particles are instantly protruded on the surface of water and are self-assembled by capillary force among the protruded particles. At the same time, the assembly of polystyrene colloidal particles is occurred on the surface of water owing to its lower effective density than water. Here we devised that the three-dimensional polystyrene colloidal crystals are quickly transferred onto the glass substrate by constructing wettable confined geometry on the glass substrate. We also applied the three-dimensional colloidal crystals to optical filters reflecting certain wavelength of light selectively by tuning the size of building blocks and incident angle of light.
