Researchers at Kobe University have designed a revolutionary "structural color ink" with dimensions as thin as 100-200 nanometers. This innovation delivers vivid colors from expansive viewing angles without fading while maintaining an impressively low weight of less than half a gram per square meter. Departing from conventional approaches utilizing parallel nanostructures, the Kobe team leverages tiny crystalline silicon spheres in their method.
The key to this breakthrough lies in Mie resonance, a phenomenon where nano-scale spheres exhibit a selective and heightened reflection of specific wavelengths. Kobe University's research not only pushes the boundaries of structural color creation but also opens avenues for lightweight, high-performance applications across various industries.
"A single layer of sparsely distributed silicon nanoparticles with a thickness of only 100–200 nanometers shows bright colors but weighs less than half a gram per square meter," says Kobe materials engineer Sugimoto Hiroshi in a press release. "This makes our silicon nanospheres one of the lightest color coats in the world."
