Research Interests

Researches on the environmentally friendly-energy conversion devices which achieves high-efficiency energy conversion such as fuel cells, storage batteries and solid-state lightings, with the goal of contributing to the global environmental problems.
One of the effective uses of ultraviolet rays (UV) is the disinfection of germs and surfaces by deep ultraviolet irradiation. UV with wavelengths below 280 nm (UVC), especially those around 265 nm, act directly on DNA of bacteria and viruses. Therefore, a technique to identify and visualize only the wavelengths corresponding to UVCs is desired. We have been working on the development of a UV wavelength visualization device using the new inorganic solid-state phosphor material. We also aim to develop a color UV camera using this technology. Our research aims at the social implementation of UV wavelength visualization technology using ceramic phosphors by conducting research and development through the fusion of mechanical engineering, material chemistry, and optics.
