Abstract
In this work, we have measured the ground state excitonic dephasing in PbS QDs of sizes from 3.7nm to 5.7nm diameter in the temperature range from 5K to 100K by transient degenerate four-wave mixing (FWM) using 100fs pulses. A combination of heterodyne and k-selection detection was implemented to increase sensitivity and enable 4 orders of magnitude dynamic range in the FWM field detection.
