A major fabrication challenge is producing disordered photonic materials with an angle-independent structural red color. Theoretical work has shown that such a color can be produced by fabricating inverse photonic glasses with monodisperse, nontouching voids in a silica matrix. Here, we demonstrate a route toward such materials and show that they have an angle-independent red color. We first synthesize monodisperse hollow silica particles with precisely controlled shell thickness and then make… Expand

Surface templated inverse photonic glass for saturated blue structural color.
The demonstrated sharp spectral selection feature can be also considered for many related applications such as sunscreens, photovoltaics and radiative cooling by adjusting the reflection transition to the required wavelength. Expand
Photonic glass for high contrast structural color
It is shown here, that the combination of a well-chosen particle geometry with the short range order of a photonic glass has strong synergetic effects and the Fourier transform required for a highly saturated color can be achieved by tailoring the substructure of the motif. Expand
