  • Assessing spatial resolution of cathodo-luminescence imaging and spectroscopy at the nanoscale for inorganic phosphor powders

    Publication
    228th ECS Meeting
    Fern, G. R.; Harris, P. G.; Ireland, T.; Silver, J.

    It is now possible to easily collect CL images (using a photomultiplier tube using total or filtered light) and emission spectra from individual nanometer sized particles using the commercially available Gatan Vulcan attachment for a transmission electron microscope (TEM).  In our case, at Brunel

  • Near-field plasmonic behavior of Au/Pd nanocrystals with Pd-rich tips

    Plasma Physics
    Ringe, E.; DeSantis, C. J.; Collins, S. M.; Duchamp, M.; Dunin-Borkowski, R. E.; Skrabalak, S. E.; Midgley, P. A.

    Using nanometer spatial resolution electron-energy loss spectroscopy (EELS), energy dispersive X-ray spectroscopy (EDS), and cathodoluminescence (CL) mapping, we demonstrate that Au alloys containing a poor plasmonic metal (Pd) can nevertheless sustain multiple size-dependent localized surface pl
