We measured the intrinsic ground-state exciton dephasing and populationdynamics in colloidal quasi two-dimensional (2D) CdSe nanoplatelets at lowtemperature (5-50K) using transient resonant four-wave mixing in heterodynedetection. Our results indicate that below 20K the exciton dephasing islifetime limited, with the exciton population lifetime being as fast as 1ps.This is consistent with an exciton lifetime given by a fast radiative decay dueto the large in-plane coherence area of the exciton center-of-mass motion inthese quasi 2D systems compared to spherical nanocrystals.

Evidence of giant oscillator strength in the exciton dephasing of CdSe nanoplatelets measured by resonant four-wave mixing
