Abstract

Increasing negative charge density at the surfaces of CdSe quantum dots (QDs) effects a bathochromic shift of their ground state optical spectra with increasing pH due to electrostatic and chemical modifications at the QD surface. These modifications are enabled by weakly-bound ligands that expose the surface to the aqueous environment.
