Colloidal photonic glasses offer an appealing way to produce vivid colors without any chemical dyes—but so far, a stubborn optical effect has long prevented them from generating a true red color. Now, ...

(Nanowerk Spotlight) From the vivid blues and greens of peacock feathers to the shimmering reds of ruby crystals, structural color in nature provides some of the most dazzling displays that delight ...

A single layer of silicon nanospheres produces bright structural colors that are independent of the viewing angle. The color can be controlled by the diameter of the spheres, where smaller particles ...

(Nanowerk Spotlight) The vibrant blue of a morpho butterfly's wings doesn't come from pigments but from light interacting with microscopic structures on its surface. This phenomenon – structural color ...

Above -The nanospheres in a methanol suspension have different colors than when applied to a surface as a monolayer. The Kobe University researchers explain, “This is due to the multiple scattering, i ...

A new way of creating color uses the scattering of light of specific wavelengths around tiny, almost perfectly round silicon crystals. This development enables non-fading structural colors that do not ...
