Abstract
Tunability of the optical stop-band wavelength and width of charge-stabilized colloidal crystals was examined theoretically and experimentally. Photonic band calculations and reflection spectroscopy indicated that the stop-band wavelength and width could be independently altered over a wide range by the combined variation of the colloidal particle size and concentration. The stop-band width of polystyrene colloidal crystals could be expanded threefold with the combined variation of the particle diameter and particle volume concentration at the fixed stop-band wavelength of red, green, and blue light. This control cannot be achieved in conventional opal-type colloidal crystals, and it is expected that the presented results will contribute towards the advanced applications of colloidal photonic crystals.
