The dynamics of quantized Auger recombination in CdSe nanocrystals was studied by femtosecond intraband pump–probe spectroscopy at room temperature. The intraband transient absorption signals increase linearly with excitation laser intensity, while the interband transient absorption signals saturate at high excitation intensities. We clarified that the excitation intensity dependence of the Auger recombination rate in nanocrystals is quantitatively explained by three-body photocarrier collision processes.
