Abstract: ZnO nanoparticles capped with thiol molecules display room temperature ferromagnetism which has been associated with the structural details of the interface formed between the organic molecule and the ZnO core. Although the local order around sulfur atoms at the ZnS/ZnO interface has been related to the occurrence of the ferromagnetic like behavior, no direct structural determination has been obtained yet. We report here a detailed x-ray absorption spectroscopy study performed at the sulfur K-edge to determine the local structure around the sulfur atoms in these systems and how it is modified by varying the length of the organic molecule.
