Photonics: Using Cuttlefish Ink as an Additive to Produce ­Non-iridescent Structural Colors of High Color Visibility (Adv. Mater. 32/2015)

Non-iridescent structural colors of high color visibility are produced by amorphous photonic structures, in which natural cuttlefish ink is used as an additive to break down the long-range order of the structure. The color hue and its spectral purity can be tuned by adjusting the diameter of the polystyrene (PS) spheres and the proportion of ink particles, as demonstrated by X. H. Liu, L. Shi, J. Zi, and co-workers on page 4719.
