Title: Dual-mode crystal-bound and X-type passivation of quantum dots

In this work, we present a new path to the control of quantum dot surface chemistry that can lead to a better understanding of nanoscale interfaces and the development of improved photocatalysts. Control of the synthetic methodology leads to QDs that are concomitantly ligated by crystal-bound organics at the surface anion sites and small X-type ligands on the surface cation sites.
