摘要
表面增强拉曼光谱(SERS)是一种高灵敏的分析检测手段,已经被广泛应用到电化学、生物传感、物理学和光催化等领域中.对SERS的研究最首要的任务是制备稳定的、高活性的SERS基底.SERS基底材料经历了由贵金属-过渡金属-半导体-贵金属/半导体复合材料的发展过程.本文对贵金属/半导体复合SERS基底的发展进行了介绍,并对其增强机理进行了简要介绍.复合基底兼具了半导体性能和贵金属基底的高增强能力,相对于单一材料体现出了更多的优越性,目前是SERS基底的研究热点.
Surface enhanced Raman spectroscopy (SERS) is a highly sensitive analytical technique,which has been widely used in the fields of electrochemistry, biosensing, physics and photocatalysis. The most important task for the study of SERS is to prepare the high sensitive and stable SERS active substrates. The SERS substrate materials have undergone the development of noble metal, semiconductor, and semiconductor/noble metal. In this paper, the development and mechanism of semiconductor/noble metal composite as SERS substrates are introduced. The semiconductor/noble metal composite SERS substrates have better performance than single metal SERS substrate or single semiconductor SERS substrate.
