(27e) Fabricating Colloidal Crystals with Different Structures and Nanostructures Derived from Them

Colloidal crystals made of polymer or inorganic microspheres have attracted extensive interest due to their potential applications in such as sensing, optical, photonic band gap and surface patterning materials. This paper describes a set of approaches to colloidal crystals of different structures including colloidal crystals with ordered voids and two-dimensional (2D) or three-dimensional (3D) patterned arrays, colloidal crystals composed of non-spherical polyhedrons, patterning colloidal crystals on nonplanar surfaces and heterogeneous colloidal crystals of different building blocks, and particularly colloidal crystals of non-close-packed colloidal spheres, which have been put up by our group. Applications of these colloidal crystals as templates for different structures range from nanoscale to submicron-meter scale have also been introduced.
