Characterization of silver sulfide nanoparticles synthesized by a simple precipitation method Article uri icon


  • Silver sulfide nanoparticles with different sizes were synthesized using a simple aqueous precipitation. Particles were obtained in the presence of three stabilizing agents controlling thus particle size and agglomeration. The particles obtained were characterized using XRD, scanning electron microscopy (SEM), transmission electron microscopy (TEM), thermal and spectroscopy techniques. We observed a size quantization effect reflected in a shift on the band gap value of smaller sample obtained. © 2004 Elsevier B.V. All rights reserved.
