Structural colored fiber fabricated by a facile colloid self-assembly method in micro-space.

Structural colored fiber was fabricated by an isothermal heating evaporation-induced self-assembly method. Under ambient white light illumination, the fibers appear colored due to optical reflectance, which is determined by the lattice constants of the photonic crystals. By controlling the size and layers of the silica nanospheres, the fiber color can be changed. This journal is © The Royal Society of Chemistry 2011
