摘要: This work deals with the characterization of ZnS NanoParticles (NP), prepared by precipitation employing thioacetamide as sulfur source at different reaction time length. The attention is focused on modification induced structural, surface and electronic properties NP post-synthesis treatments. These were aimed removing from samples adsorbed reactants, washing or thermal treatments, both in air vacuum. effect these parameters followed X-Ray Diffraction (XRD), Transmission Electron Microscopy (TEM), Fourier Transform InfraRed (FTIR), gas-volumetric ThermoGravimetric Analysis (TGA). Moreover, nanostructuration semiconducting material band gap evaluated Diffuse Reflectance UV-Vis (DR UV-Vis) spectroscopy. Density Functional Theory (DFT) calculations have been employed to clarify role reactants stability assess relationship between particle size value.
