New Transient Absorption Observed in the Spectrum of Colloidal CdSe Nanoparticles Pumped with High-Power Femtosecond Pulses

The power dependence of the transient absorption spectrum of CdSe nanoparticle colloids with size distribution of 4.0 ± 0.4 nm diameter is studied with femtosecond pump−probe techniques. At the lowest pump laser power, the absorption bleaching (negative spectrum) characteristic of the exciton spectr...
