Scientists at the University of Rochester (Rochester, NY) have created a nanocrystal that doesn't blink--in other words, after absorbing a photon, it will always radiate the energy away as another photon, rather than sometimes converting it to heat.
For more than a decade, scientists have been frustrated in their attempts to create continuously emitting light sources from individual molecules because of an optical quirk called "blinking," but now scientists at the University of Rochester have uncovered the basic physics behind the phenomenon, and along with researchers at the Eastman Kodak Company, created a nanocrystal that constantly emits light.
