Vivid, saturated structural colors are conspicuous and important features of many animals. A rich diversity of three-dimensional periodic photonic nanostructures is found in the chitinaceous exoskeletons of invertebrates. Three-dimensional photonic nanostructures have been described in bird feathers, but they are typically quasi-ordered. Here, we report bicontinuous single gyroid β-keratin and air photonic crystal networks in the feather barbs of blue-winged leafbirds (Chloropsis cochinchinensis sensu lato), which have evolved from ancestral quasi-ordered channel-type nanostructures. Self-assembled avian photonic crystals may serve as inspiration for multifunctional applications, as they suggest efficient, alternative routes to single gyroid synthesis at optical length scales, which has been experimentally elusive.

Abstract Biomimetic synthesis of amorphous photonic crystals (APCs) is a significant approach to obtain non-iridescent structural colors. However, the structural colors of artificially prepared APCs are dim or even white due to the influence of incoherent scattering. In this paper, we present an innovative method was proposed to combine APCs with black TiO2-x to construct non-iridescent structural color pigments with high visibility and photocatalytic activity. Due to absorption of incoherent scattered light by black TiO2-x, the color saturation of structural colors has been significantly increased. In addition, the utilization rate of photogenic carriers was effectively enhanced by slow light effect generated from pseudo-band gap of SiO2 APCs with TiO2-x absorbed full spectrum. The tone and color saturation of catalytic pigments are controlled by the diameter of SiO2 nanospheres and the ration of TiO2-x nanoparticles, which provides a controllable application study in color related fields such as artwork, environmental coatings and textiles.

General Method

The transmission properties of one-dimensional photonic crystals constituted by a periodic repetition of positive-index layers and epsilon-negative layers are studied theoretically. This structure shows some interesting properties including a wide gap in the low frequency range for small period number and a comb-like transmission band in the gap. The properties of the comb-like transmission band are sensitive to the period number of the structure. In contrast to the zero-ngap and the zero- φeff gap, the transmission properties are dependent on the structure parameters. A general method to decide the position of gap and transmission band in this kind of structure is also presented.
