摘要: Ultrasmall semiconductor clusters are exciting materials because of their molecularly precise structures and unique optical spectra. “Magic-sized” CdSe transformed into Cu2Se counterparts by means ion exchange. We leverage the structure high sensitivity these to investigate mechanism cation optically identify a metastable intermediate in solid-state transformation. Isolation characterization this provide insight dynamic structural rearrangement cationic sublattice course exchange role ligand passivation. Such understanding dynamics at solid–liquid interface could help engineer improved for electrolytes energy storage devices.
