摘　　要：以聚乙烯吡咯烷酮(PVP)为还原剂,在室温条件下还原银氨溶液制备纳米银片。用X射线粉末衍射(XRD)、透射电子显微镜(TEM)、紫外-可见(UV-Vis)吸收光谱对产物进行表征。结果表明,通过改变PVP用量及静置时间,可以调控纳米银片的形貌。Silver nanoflakes were reduced by silver ammonia solution with polyvinylpyrrolidone（PVP） as reductant under room temperature.The products were characterized by XRD,TEM and UV-Vis.The results indicated that the morphologies of silver nanoflakes can be tuned by changing concentration of PVP and standing time.
