Weird Nanophotonic Materials Bend and Trap Light to Make Crazy Colors
As reported on Wired. BY NADIA DRAKE Normally, the colors we perceive are determined by the wavelengths of light reflected by objects in the world around us. But not all surfaces reflect light the same way. Picture an iridescent butterfly, for example. It might look drab from one direction, but explode into bright yellows or purples from another. That’s because of microscopic structures that alter the way light bounces off the butterfly’s wings.At the NanoPhotonics Centre at the…
