中文摘要	four different sizes of citrate-protected silver nanoplates with the corresponding in-plane dipole resonance band at 530, 619, 778, and 858 nm, respectively, are synthesized for surface-enhanced raman scattering (sers) study. their aggregation behaviors are monitored by use of uv-vis spectroscopy. during the aggregation process, a marked red shift of the in-plane dipole resonance of silver nanoplates is observed, whereas other resonance modes of them only have small alterations in the site or intensity. aggregated silver nanoplates can serve as active sers substrates with an enhancement factor of about 4.5 x 10(5) using 2-aminothiophenol as a probing molecule. the sers performance of silver nanoplates is even superior to the commonly used lee-meisel silver colloid, making them very attractive for sers applications.
