Abstract

In this work, silver nanoparticles were synthesized by two methods: polyol and chemical reduction using sodium borohydride (NaBH4). In both cases, silver nitrate was employed as starting metallic salt and Poly-vinyl pyrrolidone (PVP) as surfactant agent. The average nanoparticles size was correlated by transmission electron microscopy (TEM) and quasielastic light scattering (QELS). The experimental results indicate that the average particle sizes measured by QELS were slightly higher than those obtained directly by TEM. Therefore, this work confirms that the QELS technique can give rapid and approximate average-particle size values in comparison with those obtained through TEM direct observations.
