| 中文摘要 | in this article, a novel technique for the fabrication of surface enhanced raman scattering (sers) active silver clusters on glassy carbon (gc) has been proposed. it was found that silver clusters could be formed on a layer of positively charged poly(diallyldimethylammonium) (pdda) anchored to a carbon surface by 4-aminobenzoic acid when a drop containing silver nanoparticles was deposited on it. the characteristics of the obtained silver clusters have been investigated by atomic force microscopy (afm), sers and an sers-based raman mapping technique in the form of line scanning. the afm image shows that the silver clusters consist of several silver nanoparticles and the size of the clusters is in the range 80-100 nm. the sers spectra of different concentrations of rhodamine 6g (r6g) on the silver clusters were obtained and compared with those from a silver colloid. the apparent enhancement factor (aef) was estimated to be as large as 3.1 x 10(4) relative to silver colloid, which might have resulted from the presence of 'hot-spots' at the silver clusters, providing a highly localized electromagnetic field for the large enhancement of the sers spectra of r6g. the minimum electromagnetic enhancement factor (eef) is estimated to be 5.4 x 10(7) by comparison with the sers spectra of r6g on the silver clusters and on the bare gc surface. |
