New Advance in Nano Plasmon Photonic Research at USTC

  • update:2010-03-19

        Major new findings have recently been achieved by the physical chemistry research team working on single molecules at the Hefei National Laboratory for Physical Sciences at Microscale. By integrating scanning tunneling microscopy (STM) and optical testing techniques, the researchers demonstrated for the first time that nano-cavity plasmon at the sub-wavelength scale may be used as a frequency-adjustable near-field coherent light source, thereby effectively controlling the luminescent properties of molecules and producing novel photoelectric effects: electric-thermalfluorescence, energy up-conversion luminescence, and "color" spectrum control. This discovery will open up new ways of development for point light sources, high-resolution imaging, and plasmon-based circuitry nano-optical integration technology. The study was published in the January 2010 issue of Nature Photonics [4(1), 50-54 (2010)]. Meanwhile an article entitled "Photonics: Forbidden Light" in Nature China also reported on this research. Reviewers of both publications believe that the findings, as a significant advance in nano-photonics, will draw widespread attention from researchers in the field of photonics.
