摘要

Themperature-dependent EXAFS (Extended X-ray Absorption Fine Structure) measurements between 5 and 290 K show that structural and dynamic properties of CdS nanoparticles with 13-120 A diameter depend on their par- ticle size and the way of surface stabilization. The mean Cd-S distance of thiolcapped CdS nanoparticles (13-40 A) increases with decreasing particle size with respect to CdS bulk. In contrast, mean interatomic distances in polyphosphate-stabilized particles (30-120 A) are slightly contacted.
