We have studied the optical properties of semiconductor nanomaterials such as carbon nanotubes, nanoparticles, quantum wires and wide-gap oxides. Strong Coulomb interactions between excitons confined in these nanomaterials cause fast Auger recombination and multiple exciton generation. Unique quantized recombination processes of multiple excitons are clarified using space-time resolved optical spectroscopy.
