Abstract
Abstract
We investigate the nonlinear optical properties of a series of two-photon absorbing chromophores in the femtosecond regime using both two-photon induced fluorescence spectroscopy and the Z-scan technique. We apply a simplified sum-over-states model to the experimental data to predict nonlinear refraction.

Abstract
Abstract
3D-configurated stereoisomers cis-cup-tris[C60>(DPAF-C9)] were found to exhibit photoswitchable dielectric amplification phenomena at GHz frequency. Observation was correlated to photoactivation with plasmonic energy to enhance intramolecular e‒-transfer. Accumulated plasmonic resonance energy was effective to distribute negative charges along the outer C60> fullerosome shell layer of trilayered NPs.
