Research Interests
We are developing a spatiotemporal resolution spectroscopic system by combining a time-resolved electronic (transient absorption) spectroscopy and microscopy.
Transient absorption measurement can reveal not only the electronic excited state but also all chemical species such as cations, anions, and radicals.
Currently, we are proceeding research on the following optical characteristics.
1. Development of new photo-functional nanomaterials using organic-inorganic hybrid materials.
2. Elucidation of the initial process of photoelectric conversion of organic and inorganic materials (dye-sensitized solar cells and organic thin-film solar cells).
3. Elucidation of the photoinduced nonlinear emission mechanism of organic- inorganic hybrid materials.
4. Elucidation of photochemical reaction mechanism of biological substances and organic compounds.
