  • Patent number: 8361224
    Abstract: The present invention relates to colloidal photonic crystals using colloidal nanoparticles and a method for the preparation thereof, wherein by adding a viscoelastic material into a solution containing the colloidal nanoparticles when preparing the colloidal photonic crystals, a uniform volume contraction occurs due to the elasticity of the viscoelastic material even when a nonuniform volume contraction occurs while drying a dispersion medium in the colloidal solution. Thus, it is possible to prepare 2 or 3 dimensional colloidal photonic crystals of large scale with no defects in less time.
