Optical Coating Reflects Virtually No Light
TROY, N.Y., March 1, 2007 -- Scientists have created an optical coating from a material that reflects virtually no light. The research could lead to the development of much brighter LEDs, more efficient solar cells and a new class of "smart" light sources that adjust to specific environments, among many other potential applications.From top, light reflecting off surfaces made from aluminum, silicon, and aluminum nitride.
