Daniel S. Burgess

Scientists at the Institut d’Electronique de Microélectronique et de Nanotechnologie in Lille, France, and at Utrecht University and the Mesa+ institute at Universiteit Twente in Enschede, both in the Netherlands, have determined that colloidal nanocrystals display a supralinear relation between the rate of decay of their spontaneous emission and the emission frequency. They note that the findings may offer insight into phenomena such as exciton dephasing, radiative recombination of nanocrystals in photonic crystals and Förster energy transfer. In the experiments, the researchers...Read full article

    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
