Fireflies Mimicked for Brighter LEDs

NAMUR, Belgium, SHERBROOKE, Quebec, and GRENOBLE, France, Jan. 8, 2013 — The twinkling of fireflies in the night sky inspired an international team of scientists to take the flashes on bioluminescent insects’ abdomens and apply them to a coating to increase LED efficiency. Their method proved more than one and a half times as efficient as the original LED. Other research groups have studied the photonic structures in firefly lanterns — the organs on the insects’ abdomen that flash to attract mates — as well, and have even mimicked some of the structures to enhance light extraction in LEDs, but their work focused on nanoscale features....Read full article
