EXAFS study of functionalized nanoclusters and nanocluster assemblies

Abstract

Extended X-ray absorption fine structure spectroscopy and X-ray diffraction were used to investigate the structure of CdS nanocrystals capped with different ligands. Nanocrystals capped with acetate and thiolate do exhibit the rock-salt structure, a high pressure type phase. These nanocsystals undergo a rock-salt to hawleyite transition after the thermal removal of the ligands at 200°C. Changes in coordination and distances as well as second-neighbor shells in differently capped CdS clusters are discussed in comparison with ZnS-clusters.
