Abstract

A tunable photonic crystal composition comprising: tunable photonic crystal particles having a polymer network with a periodic modulation of refractive indices, the polymer network having a reflectance wavelength, wherein the periodic modulation of refractive indices is responsive to an external stimulus and the reflectance wavelength is shifted in response to the external stimulus; and a carrier in which the particles are dispersed.
