| 摘 要： | 在恒温条件下，采用静电自组装技术在玻璃表面制备了一种具有宽等离子吸收带的纳米银膜。使用扫描电镜(SEM)观察其表面形貌发现该纳米银膜表面由粒径为18～200 nm的纳米球组成。同时从紫外可见光谱检测结果发现该纳米银膜在400～850 nm间有较宽的等离子吸收带。分别以强荧光分子(结晶紫)和生物大分子(健康人血清)作为探针分子，在近红外激发光(785 nm)下检测出了质量较好的SERS光谱。同时，分析了该纳米银膜对两种分子检测的重复性。

| Abstract: | A highly reproducible and broad plasma absorption band nano-silver film was prepared by electrostatic self-assembly technology.The size of nano-silver particles on the surface of silver film,in the scanning electron microscopy(SEM) micrograph,is in a wide distribution from 18 to 200 nm.At the same time,the ultraviolet-visible spectrophotometer was employed to detect the nano-silver film.There is a broad plasma absorption band in the UV-Vis spectrum.To test the SERS activity of the nano-silver film,crystal violet and serum of healthy person were used as probe molecules and the high quality SERS spectra were obtained. |
