Abstract

Lead sulfide nanostructures with different morphologies and particle sizes were obtained via a simple hydrothermal reaction between lead salicylate (Pb(Hsal)2) and thioglycolic acid The novelty in this synthesis is using of thioglycolic acid as a sulfur source and stability agent simultaneously. Depending on the pH of the solution, morphologies of the PbS varied and crystals with shapes of nanoparticles, flower-like nanostructures and microrods were obtained. The effect of the reaction time on the morphology of the nanostructures has been investigated. Products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) ultraviolet-visible (UV-vis) and Fourier transform infrared (FT-IR) spectroscopy.
