Abstract: A tunable photonic crystal device comprising: alternating layers of a first material and a second material, the alternating layers comprising a responsive material, the responsive material being responsive to an external stimulus, the alternating layers having a periodic difference in refractive indices giving rise to a first reflected wavelength; wherein, in response to the external stimulus, a change in the responsive material results in a reflected wavelength of the device shifting from the first reflected wavelength to a second reflected wavelength.

Abstract: A print on-demand color shift material which has high reflection, high saturation color and intrinsic, high impact color-shift produced by thermal printing or laser writing for use, for example in security laminates, tax and excise stamps, machine-readable features and banknote foils, and offering a rainbow of colors with full color shifting, producible in full manufacturing scale.
