摘要：

A novel and quick method for the synthesis of PbS and HgS semiconductor nanoparticles using mercury acetate and lead acetate as source materials and sulfur powder employed as chalcogenide source by microwave heating in polyethylene glycol (PEG) solvent is presented in this paper. HgS and PbS nanoparticles were obtained with average sizes from 20 to 30 nm in PEG, which acts as both solvent and reducing agent. The products were characterized by powder X-ray analysis, transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS). The probable mechanism was presented.
