摘要

Precipitation of lead ions by hydrogen sulfide in the presence of amphiphilic block copolymer micelles composed of polystyrene-b-poly(4)vinylpyridine yields PbS nanoparticles. By adjusting the reaction conditions with respect to the lead-to-polymer ratio, temperature or proton concentration particles of different size (2 to 20 nm) and mor- phology (spheres, cubes or needles0 have been prepared. These particles have been characterized by powder X-ray diffraction and High Resolution Transmission Electron Microscopy (HRTEM).
