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.

半导体纳米晶是一种潜在的双光子吸收敏化剂，可用于各种光化学反应。为了实现这种高效的双光子诱导光化学系统，详细的激发态性质的碲化镉纳米晶体进行了研究。利用低温含时光谱研究了CdTe纳米晶在离子液体中激发态的尺寸依赖性能量分裂。研究了分裂能态与电子转移速率的关系。
