| Summary: | In this work, we present a novel and simple solution method to synthesize cadmium
sulfide (CdS) and zinc sulfide (ZnS) nanoparticles (Nps). The solution-based processes for
CdS and ZnS were carried out at room temperature (27 °C) using sodium dodecyl sulfate
(SDS) as anionic surfactant for both chalcogenide systems. Thioacetamide (C2H5NS) was
used as anionic precursor, and as the metal precursor cadmium chloride (CdCl2) and zinc
acetate (C4H6O4Zn. 2H2O) for CdS and ZnS Nps respectively. The pH for the solution of
nanoparticles was 2.2 for CdS and 5.7 for ZnS. The conductivity for chalcogenide solution
was also determinate. Optical properties of CdS and ZnS nanoparticles were analyzed by
Ultraviolet-Visible (UV-Vis) spectroscopy; functional groups were identified by Fourier
transform infrared spectroscopy (FTIR), the surface morphology by scanning electron
microscopy (SEM) and the crystalline structure by X-Ray diffraction (XRD). The
distribution size for nanoparticles were less than 100 nm for CdS and ZnS Nps. |
