| Research Abstract |
We tried the development of electromagnetic radiation source using the method taken out as light by generating surface plasmons when the electron beam runs along the surface of metallic diffraction gratings. The optical radiations caused by the generation of surface plasmons were observed in wavelengths that were longer than the Smith-Purcell radiation. Moreover, in the organic EL devices, there is a problem of the optical absorption by surface plasmons in the interface of a metal electrode and an organic film. Surface roughness formed on the metal interface scatters the surface plasmons as light. We experimentally observed that the emission of light to air side from dye doped organic film can be enhanced with this surface roughness effect.
