Popis: One-dimensional silver nanowires with uniform diameters and different aspect ratios were solvothermally synthesized by reducing silver nitrate with ethylene glycol(EG) in the presence of poly(vinylpyrrolidone) (PVP) and ferric chloride (FeCl3) at different temperatures for a certain time. The effects of reaction temperature on the yield and morphology of silver nanowires were carried out to discuss by a series of experiments, then the products were purified and characterized by ultraviolet-visible spectroscopy, X-ray diffractometer and field emission scanning electron microscopy, respectively. The experimental results indicated that although silver nanowires were formed from 145 ℃ to 170 ℃, the silver nanowires had the highest yield and the most uniform aspect ratio when the reaction temperature was 155 ℃ for 2.5 h in polytetrafluoroethylene autoclave.
