Outline of Final Research Achievements

Terahertz spectroscopy provides information on lattice vibration or higher-order structure of organic materials and organic nanomaterials. In this study, we aimed to elucidate specific properties of these organic materials by using terahertz spectroscopy and fluorescence spectroscopy which provides information on behavior of excitons. We also aimed to develop a new technique for highly sensitive terahertz spectroscopy. Organic electro-optic polymers have large electro-optic coefficients and are expected as the promising materials to generate terahertz waves. We elucidated properties of the organic electro-optic polymers in terahertz region. We confirmed highly efficient generation of terahertz waves from the organic electro-optic polymer films.
