| Research Abstract |
Fundamental technologies were developed to achieve spectroscopic measurements with very high spatial resolution and time resolution at the same time. Studies were also done to obtain fundamental knowledge for exploring wave characteristics of excited states of nanomaterials and manipulating them. We succeeded in visualization of wavefunctions of photo-excited states and spatial distributions of photons for various metal nanostructures, and revealed novel optical characteristics through the analyses of the observed images. We also obtained information on dynamics via time- and space-resolved spectroscopic measurements.
