The three-pulse echo peak shift method was used to quantify both the homogeneous and inhomogeneous broadening contributions to the absorption spectra of nanocrystals. Evidence showed that, at room temperature, the homogeneous broadening of the optical absorption spectrum of CdSe nanocrystals is comparable to the inhomogeneous broadening attributed to the size distribution of ∼10%.
