The relaxation pathway of the excited charge carriers in CdSe nanoparticles (NP) was monitored by the spectral dynamics in the visible, near-infrared (NIR), and infrared (IR) range. The observed dynamics was assigned to the electron or the hole using electron and hole quenchers to the photoexcited NPs. A decay time of 1.2 ps was found for the transient absorption observed in the NIR.
