About us

Kajihara Lab. is a new laboratory, launched on April of 2018. In FY2020 Prof. Takashi Takei and Prof. Takashi Yanagishita have joined. We are studying photo-electrofunctional inorganic solids and related materials including ceramics and glasses, which are key materials serving as sustainable urban environment and low-carbon economy. Research interests include development of environment-friendly processes, search and structural-compositional modifications of materials, and their application to functional devices such as phosphors, lasers, and batteries.

Research area

  • Inorganic materials chemistry
  • Functionalization of ceramics, glasses, and silicon-based organic-inorganic hybrids
  • Silica and their applications to optical materials
  • Environmental-friendly synthesis of inorganic materials
  • Efficient energy conversion with inorganic materials
  • Photoinduced phenomena, diffusion, and chemical reactions in/on inorganic solids
  • Studies on formation of nanostructures by self-organizing processes
  • Studies on precision separation
  • Studies on energy devices and optical devices
