| 中文摘要: |
| 采用晶种诱导的方法合成了超长银纳米线，用扫描电镜(SEM)、透射电镜(TEM)、选区电子衍射(SAED)、X射线衍射(XRD)和紫外可见光谱(UV-Vis)等表征手段考察了制备条件对晶种和银纳米线的影响。结果表明，AgNO3浓度对晶种和银纳米线的形貌有影响。在优化条件下，5 min内即可诱导合成长度为70~100 μm，直径为90~200 nm的具有良好均一性的 超长银纳米线。 |
| 英文摘要: |
| Ultra-long silver nanowires (AgNWs) were synthezised via a short AgNMs seeds-directed (SNS-directed) route, and the influence of preparative conditions on the seeds and AgNWs were investigated by using different analytical methods including SEM, TEM, SAED and XRD and UV-Vis. The results indicated that AgNO3 concentration had effect on SNS and ultra-long AgNWs. Under the optimized SNS-directed conditions, the uniform ultra-long AgNWs with a length of 70~100 μm and a diameter of 90~200 nm developed in 5 minutes. |
