Abstract
Colloidal crystallization is principally a 3-dimensional self-assembling phenomenon of monodisperse spherical colloidal particles based on electro-static repulsion between particles. The 3-dimensinal particles array systems are recently receiving mach attention for application to photonic devises, because of inducing visible light diffraction. In this paper, our recent studies concerning the colloidal crystallization of polymer-modified silica in organic solvents and the immobilization of the crystal in gel and polymer matrices are reviewed.
