چکیده:

Silver nanowires with adjustable diameters ranging from 60 to 90 nm and lengths of more than 50 μm have been synthesized by introducing certain control agents into the conventional polyol process. It is presumed that the control agents could influence the size of initial nucleus and therefore the diameters of the final nanowires through forming silver salt colloids or varying the rate of silver reduction. Approximately, 70% of the metallic silver formed in the reduction consists of silver nanowires. Characterization of the silver nanowires has been done by XRD, SEM and UV– vis absorption spectra.
