| Outline of Final Research Achievements |
The purpose of this study is to explore time and spatially resolved resolved deep ultraviolet spectroscopy and to reveal the optical properties of ultra-wide bandgap semiconductors. In the former, we developed a deep-ultraviolet scanning near-field optical microscope which has the shortest excitation wavelength ever reported. In the latter, we revealed the isotopic effect on excitons in diamond using deep-ultraviolet photoluminescence spectroscopy. We observed a deep-ultraviolet emission from nano-polycrystalline diamond. We observed localized emissions from AlGaN quantum well structures using a deep-ultraviolet scanning near-field optical microscope.
