In this article, the results of femtosecond three-pulse photon echo peak shift (3-PEPS) measurements are reported for a series of cadmium selenide core-shell semiconductor nanocrystals. The peak shift data were found to be highly dependent on the shell compositions and particle morphologies. The static inhomogeneity parameter was found to vary from 10 cm(-1) for highly isotropic particles to 170 cm(-1) for particles with a broad size distribution. We also discuss the high-frequency (approximate to 212 cm(-1)) longitudinal optical (LO) phonon and the low-frequency (approximate to 13-19 cm(-1)) longitudinal acoustic (LA) phonon modes (omega(00)) and how the damping times and frequencies also depend on the choice of capping material.
