This study discusses the effect of FeCl3 concentration over synthesis of silver nanospheres and nanowires (NWs) by reducing silver nitrate (AgNO3) with ethylene glycol through a simple polyol method and using poly(vinylpyrrolidone) as capping agent. X-ray diffraction (XRD), ultraviolet visible spectroscopy, scanning electron microscopy and transmission electron microscopy were performed in order to find the structural and geometrical features of silver nanostructures. XRD analysis confirmed formation of metallic silver phase and microscopic studies revealed formation of NWs with average diameters ranging from 50 to 100nm. Different concentrations of ferric chloride (FeCl3) are used to control the morphology and shape changes of primary silver seeds. A mixture of silver nanospheres and NWs are formed at 0.05mM concentration of FeCl3 while increasing the concentration of FeCl3 to 0.1mM lead to formation of silver NWs. Moreover, an increase in the concentration of FeCl3 from 0.1 to 0.3mM results in reduction of aspect ratio of silver NWs. Furthermore, more increase in FeCl3 concentration from 0.3mM results again in formation of semi spherical shapes silver nanostructures.
