Patent

CA 2731778

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 mod-ulation of refractive indices is responsive to an external stimulus and the reflectance wavelength is shifted in response to the exter-nal stimulus; and a carrier in which the particles are dispersed.

La présente invention concerne une composition cristalline photonique syntonisable comprenant : des particules cristallines photoniques syntonisables présentant un réseau polymère à modulation périodique dindices de réfraction, le réseau polymère présentant une longueur donde de réflectance, la modulation périodique dindices de réfraction étant sensible à un stimulus externe et la longueur d'onde de réflectance étant décalée en réponse au stimulus externe ; et une charge dans laquelle les particules sont dispersées.
