Berkeley Lab Scientists Find Unique Luminescence in Tetrapod NanocrystalsBerkeley CA (SPX) Jul 05, 2011 Observation of a scientific rule being broken can sometimes lead to new knowledge and important applications. Such would seem to be the case when scientists with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) created artificial molecules of semiconductor nanocrystals and watched them break a fundamental principle of photoluminescence known as "Kasha's rule." Named for chemist Michael Kasha, who proposed it in 1950, Kasha's rule holds that when light is s ... read more |
