| 摘 要： | 采用热注入法，以AgNO3为前躯体，乙二醇为还原剂，聚乙烯吡咯烷酮为稳定剂和分散剂，制备银纳米颗粒。利用透射电子显微镜（TEM）、X射线衍射仪（XRD）和紫外-可见光分光光度计（UV-Vis）对产物银颗粒的尺寸形貌、晶体结构以及光学性能进行了表征，同时根据Mie散射理论对消光谱进行模拟计算。结果表明，同传统的一步化学还原法相比，利用热注入法制备的银纳米颗粒粒径分布更加均匀，分散性更好。所制备的银颗粒呈类球形，粒度约为20 nm，其共振吸收谱线同模拟计算的结果基本符合。

| Abstract: | Silver nanoparticles have been synthesized by the reduction of AgNO3 in the presence of polyvinyl pyrrolidone as surfactant and ethylene glycol as reducing agent through a hot-injection method. The size distribution, morphology, structure and optical properties of particles have been characterized by transmission electron microscopy (TEM), X-ray diffractometer (XRD) and UV/Visible absorption spectrophotometry. While the absorption spectra was investigated by means of Mie theory. Results indicate that comparing to the traditional one-step reduction routes, the silver nanoparticles, derived from hot-injection method, possesses a better dispersion and more uniform size distribution. TEM images show that the morphology of nano-silver particles are spheroidal, with an average diameter of 20 nm, and the experimental observations are basically consistent with the numerical analysis results. |
