| Outline of Final Research Achievements |
Various type polarizations of elemental excitation are existed in the crystal. The information of the polarization structure induces various application. In this study, we tried to perform visualize the radiative and non-radiative polarization structure by scanning of multi-nearfield probes. So far, we realized to excite one of the non-radiative multipole exciton states by one photon process. The result shows that the interaction between Laser and matters is different from spontaneous emission light and one. In addition, luminescence color has been shown to be controllable by modulating the light beam shape.
