摘要: Magic-sized clusters (MSCs) can provide valuable insight into the atomically precise progression of semiconductor nanocrystal transformations. We report conversion an InP MSC to a Cd3P2 through cation exchange mechanism and attempt shed light on evolution physical electronic structure during transformation. Utilizing combination spectroscopic (NMR/UV–vis) structural characterization (ICP-OES/MS/PXRD/XPS/PDF) tools, we demonstrate retention original crystal lattice as Z-type ligand initially occurs. Further induces relaxation significant rearrangement. These observations contrast with reports in quantum dots, indicating unique reactivity MSC.
