Kobe College researchers have designed a revolutionary “structural coloration ink” with dimensions right down to 100-200 nanometers. This innovation delivers vivid colours from expansive viewing angles with out fading whereas sustaining an impressively low weight of lower than half a gram per sq. meter. Ranging from standard approaches that use parallel nanostructures, Kobe's staff exploits tiny spheres of crystalline silicon of their technique.
The important thing to this discovery lies in Mie resonance, a phenomenon the place nano-scale spheres exhibit selective and enhanced reflection of particular wavelengths. Kobe College's analysis not solely pushes the bounds of making structural coloration, but additionally opens up avenues for light-weight, high-performance functions in numerous industries.
“A single layer of sparsely distributed silicon nanoparticles with a thickness of solely 100-200 nanometers reveals vivid colours, however weighs lower than half a gram per sq. meter,” says Kobe supplies engineer Sugimoto Hiroshi in a press launch from press. “This makes our silicon nanospheres one of many lightest coloured layers on this planet.”
