Researchers say photoluminescence is phenomenon that triggers emissions (Image 3)

Rice University researchers (from left) Yi-Yu Cai, Behnaz Ostovar and Lawrence Tauzin are looking into the source of light emitted by plasmonic metal nanoparticles. In a new paper, they argue for the dominance of photoluminescence as opposed to Raman scattering -- the elastic scattering of a photon ...This is an NSF Multimedia Gallery item.
