| 摘 要： | 采用盐酸羟胺种子生长法制备60 nm左右的粒径均一的金纳米粒子, 通过在ITO上修饰3-氨基丙基-三甲氧基硅烷(APTMS)对金纳米粒子进行组装, 得到组装密度较高、均一的表面增强拉曼光谱(SERS)基底; 采用等离子体清洗再用醋酸溶液浸泡除去氧化层的方法, 可获得干净的SERS基底, 这种方法与其它基底除杂方法相比更为简单、操作性强且信号只衰减了20%。

| Abstract: | Gold nanoparticles with uniform size and shape distribution were synthesized by hydroxylamine seed-mediated growing method.High density and uniform SERS(surface-enhanced Raman spectroscopy) substrates were obtained by assembling Au nanoparticles on the indium tin oxide(ITO) substrates which had been modified with(3-aminopropyl) trimethoxysilane(APTMS).Clean SERS substrates have been obtained by cleaning the assembled substrate in Plasma cleaner followed by immersion in acetic acid to remove the surface oxid... |
