DESCRIPTION
Researchers have discovered that the ancient technique of heating metal to create vibrant colors creates a nanostructured surface that acts as a perfect light absorber. Perfect light absorbers—materials that absorb more than 99% of a certain color—can be used for sensing, solar panels, anti-counterfeiting and stealth technologies.
