Ion Trap Ion Mobility Mesurement System

Dye-Sensitized Solar Cells

Carrier dynamics in dye-sensitized solar cells (DSSCs) are investigated by spectroscopic techniques, and will be utilized for getting the maximum conversion efficiecy out of DSSCs.

Gold Clusters and Nanoparticles

We synthesize gold clusters and nanoparticles in liquid phase, and utilize their optical properties, photoluminescence and surface-enhanced Raman scattering, with one particle or self-assembled paricles.

Separation of Carbon Nanotubes

Semiconducting single-walled carbon nanotubes are selectively extracted to the liquid phase in aqueous thermoresponsive polymer above LCST.
