| 摘 要： | 以聚乙烯吡咯烷酮(PVP)作为表面活性剂,利用乙二醇溶剂热法成功制备了银纳米颗粒;利用场发射扫描电子显微镜(FE-SEM)、透射电子显微镜(TEM)、X射线衍射(XRD)分析了样品的形貌和晶体结构,并考察了溶剂组成等因素对银纳米颗粒形貌的影响.研究结果表明所得银纳米晶粒径均一,直径约为90nm;增大PVP的加入量会降低产物的粒径,溶剂中水的引入会影响银纳米晶的形貌.

| Abstract: | Silver nanoparticles with a narrow size distribution were fabricated via a facile solvothermal route in glycol in the presence of polyvinylpyrrolidone(PVP) as the surfactant.The morphology and crystal structure of as-synthesized silver nanoparticles were analyzed by means of field-emission scanning electron microscopy,transmission electron microscopy,and X-ray powder diffraction.Moreover,the effect of solvent composition on the morphology of silver nanoparticles was explored.The results showed that the obta... |
