Size- and Site-Dependent Reconstruction in CdSe QDs Evidenced by Se{H} CP-MAS NMR Spectroscopy.

Evidence of size-dependent reconstruction in quantum dots leading to changes in bonding is observed through analysis of the Se{H} cross-polarization magic angle spinning and Se spin-echo solid-state NMR for CdSe quantum dots. The CP-MAS and spin-echo data indicate discrete surface and core Se sites...
