Unraveling Phonon Couplings in a Cdse/ZnS Colloidal Quantum Dot Ensemble Using Two-Dimensional Coherent Spectroscopy

Abstract

We resolve the phonon structure from from lowest exciton transition of CdSe/ZnS quantum dots ensemble by separating the homogeneous and inhomogeneous linewidths through optical multidimensional coherent spectroscopy at low temperatures.
