Abstract

The influence of lower temperature on size and polydispersity of silver nanoparticles prepared by reduction of the silver(I) diamine complex cation by sodium borohydride was studied. The preparation was carried out in ethylene glycol and ethanol in the presence of stabilizing agents. Silver nanoparticles were characterized by UV-Vis spectroscopy, dynamic light scattering (DLS) and transmission electron microscopy (TEM). The best results were achieved in ethanol. The smallest nanoparticles were prepared at the reaction temperature of -5 °C (3,4±1,7 nm). With decreasing temperature, the average size of silver nanoparticles increased up to 7,2±2,9 nm (-25 °C).
