| Uniform silver nanowires have been synthesized by the reduction of AgNO3 in the presence of polyvinyl pyrrolidone as surfactant and ethylene glycol as reducing agent through improved solvothermal method, wherein the silver nanoparticles were used as the crystal seeds. The morphology, structure and optical properties of silver nanowires have been characterized by X-ray diffractometer(XRD), scanning electron microscopy(SEM), transmission electron microscopy(TEM), and UV/Visible absorption spectrophotometry. Results indicate that, the silver nanowires, derived from the improved solvothermal approach, possesses high aspect ratios and uniform size distribution. In addition, the products are in a fine dispersion and exhibit obvious surface plasmon resonance characteristics. |
