| Research Abstract |
We have succeeded to develop a method for producing highly oriented bulk colloidal photonic crystals by means of shear-induced process. Crystals with different lattice constants are also produced by changing particle concentration and particle radius. Obtained materials are stable solid where three-dimensional periodic particle arrays are immobilized in a plastic polymer matrix, and are cut in desired shapes. In addition, depending on the condition of the shearing process, unexpected optical characteristics are found to be manifested in the materials.
