Daniel S. Burgess

Researchers at the University of Massachusetts Amherst and at Oak Ridge National Laboratory in Tennessee have observed far-field modulated fluorescence lifetimes indicative of dipole-dipole coupling in semiconductor polymer nanostructures. The phenomenon has potential applications in the development of components for scalable photonic information systems. Michael D. Barnes, an associate professor of chemistry at the university, said that the investigators dubbed the structures "nantennae" because of their scale -- on the order of 10 nm -- and because they interact over distances of microns...Read full article
