Abstract

Nanoparticles of lead sulfide, selenide and telluride have been synthesized by the reduction of sulfur, selenium or tellurium powder with sodium borohydride (NaBH4) to produce sulfide, selenide or telluride ions, followed by their reaction with a lead salt. In comparison to the chloride, nitrate or sulfate, considerable control of the product is possible when lead carbonate is used as the salt; various shapes of nanoparticles are obtained on varying temperatures and/or times of reaction. The nanoparticles were characterized by infrared spectroscopy (IR), powder X-ray diffraction (PXRD), transmission electron microscopy (TEM), high resolution transmission electron microscopy (HRTEM) and X-ray photoelectron spectroscopy (XPS).
