表面增强拉曼散射基底的研究进展

表面增强拉曼光谱(SERS)由于其高的灵敏度、抗干扰能力强等优点,被广泛应用在表面科学、分析化学、物理学等领域,是研究表面和界面过程的重要工具,是定性鉴定化学组成相近化合物的有力手段.因此,高品质、高活性的SERS基底一直是科研工作者们追求和研究的重点.本文对SERS活性基底的发展进行了介绍,从金、银金属纳米粒子作为基底的拉曼效应的科学研究,又进一步总结了非金属纳米粒子ZnO、TiO₂、ZnS、Cu₂O、CdTe、CdS等SERS基底.今后,将贵金属与半导体纳米材料复合将是SERS基底的研究热点.SERS光谱目前可以在液相色谱分析的检测器、医学检测仪器、刑侦分析检测等众多领域得到应用.

Review on surface enhanced Raman scattering substrates

Due to its high sensitivity and strong anti-jamming ability,surface-enhanced Raman spectroscopy (SERS) is widely used in surface science,analytical chemistry,physics and other fields,and is a powerful tool for qualitative identification of compounds with similar chemical composition. Therefore,SERS substrates with high-quality and high-activity have always been a focus of researchers. Gold and silver metallic nano-particles based on the Raman effect were first introduced; and non-metallic nanoparticle,ZnO,TiO₂,ZnS,Cu₂O,CdTe,CdS etc,as surface-enhanced Raman substrate were then summarized in terms of the SERS signal enhancement. Surface-enhanced Roman spectroscopic is currently applied in the liquid phase chromatographic detectors,medical instrumentation,forensic analysis and testing,and many other fields. In the future,the substrates of the complex of metal/semiconductor materials shall be focused on.
