The CdS nanoparticles with Cd2+-rich surface are capped by the electrically neutral ligand of 2,2-bipyridine (bpy), and the counterion, BPh4-, is adsorbed around the particle as balance charge. The σ donation from 2,2-bipyridine at 2-position to the Cd2+-rich surface of the CdS nanoparticles was characterized by X-ray photoelectron spectroscopy (XPS). These CdS nanoparticles can redisperse in pyridine (py) or DMF, and have high stability. The determination of electroconductivity and the electrophoresis deposition in dilute solution containing the CdS nanoparticles further prove the rationality of the above electrolyte structure of the CdS nanoparticles 关键词: cadmium compounds;colloids;electrophoretic coating techniques;II-VI semiconductors;materials preparation;nanostructured materials;X-ray photoelectron spectra;nanoparticles synthesis;nanoparticles characterization;strong electrolyte behavior;colloidal chemical method;Cd2+-rich surface;electrically neutral ligand;2,2-bipyridine;adsorbed counterion;X-ray photoelectron spectra;XPS;electroconductivity;electrophoresis deposition;dilute solution;CdS
