| Outline of Final Research Achievements |
Optical characterizations with a high spatial resolution are fundamental importance to unravel photo-physical processes in nanomaterials. Optical microscope is of great use for this purpose. However, spatial resolution is limited by diffraction of light. In this study, we developed an advanced cathode-luminescence spectro-microscope, which achieves a nanometer spatial resolution, by combining a phase-step luminescence spectroscopy with a low vacuum compatible scanning electron microscope. We applied the developed method to various nanometerials and clarified its effectiveness and versatility. Moreover, We developed a novel fabrication protocol for organo-luminescent nanoarchitectures. The methods developed in this study are promising for detailed characterization of the nanomaterials.
