| 摘 要： | 在以聚赖氨酸为表面耦联层分子的玻片基底制备了银纳米粒子阵列。ＳＥＭ表征结果表明，银粒子以亚单层的形式排列在基底表面。比较银溶胶和纳米粒子阵列的紫外可见光谱可见聚赖氨酸耦联层对银纳米粒子的粒径具有一定的选择性，甲基紫精在银纳米粒子阵列上的表面增强ＦＴ拉曼光谱表明在近红外区拉曼散射的表面增强主要来自于化学增强效应。

| Abstract: | Planar arrays of nano structured silver particle were self assembled on poly lysine modified glass surfaces.SEM characterization indicates that silver particles were assembled as a sub monolayer.A comparison of the UV/Vis spectra of silver colloid and the arrays demonstrates that the poly lysine layer showed size selectivity for the self assembling silver particles.Surface enhanced FT Raman spectrum of methylviolegen on the array reveals that Raman scattering in near IR region was mainly enhanced via a chemical enhancement mechanism. |
