Título : Tunable Colors in Opals and Inverse Opal Photonic Crystals
Fecha de publicación : 16-ene-2013
Editorial : InterCience
Descripción : Colloidal photonic crystals and materials derived from colloidal crystals can exhibit distinct structural colors that result from incomplete photonic band gaps. Through rational materials design, the colors of such photonic crystals can be tuned reversibly by external physical and chemical stimuli. Such stimuli include solvent and dye infi ltration, applied electric or magnetic fi elds, mechanical deformation, light irradiation, temperature changes, changes in pH, and specifi c molecular interactions. Reversible color changes result from alterations in lattice spacings, fi lling fractions, and refractive index of system components. This review article highlights the different systems and mechanisms for achieving tunable color based on opaline materials with closepacked or non-close-packed structural elements and inverse opal photonic crystals. Inorganic and polymeric systems, such as hydrogels, metallopolymers, and elastomers are discussed.
