| Research Abstract |
Semiconductor nanocrystals were demonstrated as a potential excellent two-photon absorption sensitizer for various photochemical reactions. To achieve such efficient two-photon induced photochemical system, the detailed excited state properties of CdTe nanocrystals were investigated in this study. The size-dependent energy splitting in the excited state of CdTe nanocrystals were evaluated by the low-temperature and time-dependent spectroscopy in an ionic liquid matrix. The relationship between the split energy states and electron transfer rate was also investigated.
