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. ​
