摘　　要：表面增强拉曼散射(surface-enhanced Raman scattering,SERS)在分析检测领域中具有重要地位,然而随着其不断发展,贵金属SERS基底在实际应用中受到限制.基于C,Ti,Zn,Cu,Mo,W等非贵金属纳米材料的SERS基底相比于贵金属基底具有更优异的经济性、稳定性、选择性以及生物相容性等,逐渐被广泛研究和应用.并且由于其化学增强占主导的特性,非贵金属基底为SERS化学增强机理的研究提供了理想的平台.因此,本文对近年来非贵金属SERS基底的发展进行了综述,讨论了不同材料的增强机理及SERS性能,并探讨了其未来的研究与发展方向.Surface-enhanced Raman scattering(SERS)is of great importance in analytical science,the noble-metal such as gold and silver are widely used in SERS research and applications.However,noble-metal based substrates are hampered in practical application.As for comparison,the Non-noble metal especially the semiconductor materials are the emerging SERS research frontier.Non-noble metal(such as C,Ti,Zn,Cu,Mo,W,etc.)nanomaterials based SERS substrate have been widely studied and applied due to their superior stability,selectivity,biocompatibility and low cost comparing to noble metal materials.As the chemical enhancement dominate its total SERS signals,it also provides an ideal platform for the investigation of chemical enhancement mechanism.In this review,we explored the development of non-noble metal SERS substrates,focusing on its enhancement mechanism and SERS performance of different materials as well as the future development direction.
