Abstract

A dually tunable photonic crystal composed of thermosensitive gel particles confined in a pH-sensitive inverse-opal gel is reported. The position of the photonic band-gap can be thermally regulated, while its intensity is dramatically changed by pH. Reversible, independent, and extensive switching of the position and intensity of the photonic band-gap could be achieved using independent external stimuli.

36. The change in the swelling degree of the inverse‐opal gel was estimated using the spectroscopically observed values ofλmaxand Equation 1. The following values were used for each parameter to calculate the value ofD/D0:d = 233 nm;m = 1. refractive index of water = 1.334; refractive index of the HEMA–AAc gel = 1.435; volume fraction of water spheres = 0.74; and volume fraction of HEMA–AAc gel = 0.26. Thenavalue of 1.36 is thus obtained.
