Structural Properties of PbS Nanoparticles Prepared by Photo Chemical Synthesis

Abstract:

Lead sulfide (PbS) nanoparticles have been synthesized by photo chemical method and also in the dark ambient at room temperature. The pH of the solution is maintained by adding NaOH. The as-prepared PbS nanoparticles have been characterized by X-Ray Diffraction (XRD), Scanning electron microscopy (SEM), Energy-dispersive Analysis of X-ray (EDAX) and Transmission Electron Microscopy (TEM). XRD studies reveal the crystalline nature of the particles. Grain size values are calculated using Scherrer’s formula and compared with the standard values. SEM picture shows a flower like structure in the sample synthesized at dark ambient, whereas the samples synthesized in light reveals the presence of varied nanostructures like nanorods, nanowires and nanoparticles. Size of the photo chemically synthesized PbS particles observed from TEM lies between 30nm to 60nm. From EDAX we conclude that the composition is nearly stoichiometric.
