Top Stories of 2015 from Photonics.com
Flexible Film Creates Colors from Reflected Light June 2015 A team at the University of Central Florida’s College of Optics and Photonics (CREOL) in June developed an ultrathin, color-changing film that reflects rather than emits light. This could potentially change the clothing we wear, in addition to enhancing displays. FIGURE GOES HERE====A National Geographic photograph of an Afghan girl is used to demonstrate the color-changing abilities of the nanostructured reflective
