摘要
采用微波辅助三乙醇胺还原法制备了表面高度分支化、具有较高表面增强拉曼散射(surface-enhanced Raman scattering,SERS)活性的金纳米花(gold nano-flower,AuNF)溶胶。利用透射电镜(trarsmission electron microscopy,TEM)表征AuNF的形貌与粒径大小,并以维多利亚蓝B(Victoria blue B,VBB)为探针分子测SERS光谱,结合金纳米花溶胶的紫外-可见吸收光谱、共振瑞利散射光谱,可判断微波20s条件下制备的AuNF溶胶其SERS活性最强。
A gold nano -flower （AuNF）with height branching surface and high surface enhanced ramanscattering （SERS）activity was prepared by microwave assisted reduction.The morphology and particle size ofAuNF were characterized by transmission electron microscopy （TEM）,the SERS spectra were measured byusing Vitoria blueB （VBB）as probe molecule,combining with UV-vis absorption spectra and resonancerayleigh scattering spectra of AuNF could be concluded that the AuNF sol prepared by microwave 20 s had thestrongest SERS activity.
