| Research Abstract |
Cathodoluminescence detection system has been developed, which enables us to measure the angle-resolved spectrum of emitted light from nano-scale area, when a material is illuminated by an electron probe accelerated by a low voltage. Size of the electron probe reached to sub-nanometer scale at 80 kV by using a scanning transmission electron microscope equipped with a spherical aberration corrector and a newly produced parabolic mirror. Light emission from a gap plasmon antenna formed between a silver nanoparticle and silver surface was observed, and a characteristic dispersion relation of surface plasmon polariton in 1D-and 2D-plasmonic crystals was found in angle-resolved spectral images.
