Probing the Influence of Shell Configurations on the Exciton Dephasing of CdSe Colloidal Quantum Dots Using Multidimensional Coherent Spectroscopy

Abstract

Using multidimensional coherent spectroscopy, measurements of exciton dephasing, acoustic phonon confinement and fine structure splitting were obtained for CdSe colloidal quantum dots with different shell configurations, enabling identification of the shell's influence over these properties.
