Abstract
We report a significant improvement of the tuning stability of the colloidal photonic crystal composed of long-range ordered crystalline colloidal arrays through modifying the ITO electrode with ion exchange resins. Thin layer of over-coating on ITO resulted in significantly improved number of switching of stable colour tuning from red to green over 800 times, which is reported best result for tunable photonic crystal with more than 100 nm of Δλ.
