摘    要:本文制备了不同形貌的金纳米颗粒,并对其形貌对光学性能的影响进行了研究。本文用还原法制备了不同粒径的金纳米颗粒,采用晶种生长法成功地制备出了星形、梭形和棒状的金纳米颗粒。颗粒的形貌和大小并采用投射电子显微镜(TEM)进行了表征,结果说明,本文成功制备出了不同形貌大小的金纳米颗粒。UV-Vis光谱和拉曼光谱仪对制备的颗粒的表征测试说明,不同形貌大小对颗粒有着不同的光学性能。拉曼光谱的结果说明,不同形貌大小的金纳米颗粒可以用作不同浓度分子的探针,对物质进行检测。

关 键 词:星形金纳米颗粒  球星金纳米颗粒  表面增强拉曼散射(SERS)  晶种生长法(晶种法)

Abstract:This paper presents an approach to synthesis of gold nanoparticles with different morphologies and investigation of the relationship between morphologies and their optical properties.Spherical gold nanoparticles with different sizes are synthesized via reduction method.Using seed-mediated solution growth method,gold nanoparticles with shuttle,star and stick shapes can be obtained.The sizes and morphologies of the gold nanoparticles are characterized by transmission electron microscopy (TEM).The characterization results illustrate the growth process of the gold nanoparticles with different morphologies.Absorption spectroscopy and Raman spectroscopy measurements are performed to demonstrate the relationship between the morphologies and optical properties.The results of Raman characterization show that the gold nanoparticles with different morphologies can be used to probe molecules with different concentrations.
Keywords:star-shaped gold nanoparticles  spherical gold nanoparticles  surface-enhanced Raman scattering (SERS)  seed-mediated solution growth method
