We report on the dynamical properties of photoexcited carriers, particularly the charge transfer, in CdS–CdSe–CdS segmented nanorods using femtosecond transient pump–probe spectroscopy. Design of this kind of heteronanostructures with the possibility of variation of the relative volumes of CdS and C...
