| Research Abstract |
II-VI semiconductor nanocrystals (CdS，CdSe，CdTe，PbS) were prepared by colloidal synthetic methods and their interfacial properties were controlled by interfacial engineering using various capping reagents, shells, and metal nanoparticles. Carrier dynamics of these nanocrystals were examined by femtosecond transient absorption, time-resolved emission, and single particle spectroscopy. Effects of interfacial structures and phonons on single exciton dynamics and Auger recombination due to the interaction of multiple excitons were analyzed together with the temperature dependence on carrier dynamics.
