| 摘 要： | 利用相转移法合成了在有机溶剂中有很好分散性的十二胺表面修饰金纳米粒子。通过调节金盐与十二胺的物质的量比可以得到不同尺寸分布的金纳米粒子，其中刀（金盐）：n（十二胺）=1：10时，平均粒径最小，并且以选择性沉淀分离法将其分离成尺寸不同、接近单分散的3部分：运用紫外可见光谱（UV-vis），红外光谱（IR）、X-射线衍射（XRD）和透射电镜（TEM）对金纳米粒子进行了相关表征和分析。

| Abstract: | Laurylamine-capped Au nanoparticles were synthesized by phase transfer method. The prepared nanoparticles can be well dispersed in organic solvents. The different size distributing of Au nanoparticles can be controlled by adjusting the molar proportion of auric salt and laurylamine. When the molar proportion is 1：10, the average size of the particles is the smallest and was separated into three portions with different sizes and near monodispersity by the method of selective deposition. UV-vis absorption spectroscopy, infrared spectroscopy, XRD and TEM were used to characterize and analyze the prepared nanoparticles. |
