| Research Abstract |
We developed a new cathodoluminescence detection system equipped with a scanning transmission electron microscope(STEM), which enables an angle-resolved spectrum measurement for an electron beam induced light emitted from a sample in the STEM. Using this system, we investigated conversion process between a surface plasmon polariton(SPP) and a photon through surface nano-structures involving plasmonic crystals. Characteristic property of SPP propagation on wave guides and the enhancement mechanism of luminescence due to a localized electric field of surface plasmon were also studied.
