Abstract

Surface-enhanced Raman scattering (SERS) and tip-enhanced Raman scattering (TERS) have opened a variety of exciting research fields. However, although a vast number of applications have been proposed since the two techniques were first reported, none has been applied to real practical use. This calls for an update in the recent fundamental and application studies of SERS and TERS. Thus, the goals and scope of this review are to report new directions and perspectives of SERS and TERS, mainly from the viewpoint of combining their mechanism and application studies. Regarding the recent progress in SERS and TERS, this review discusses four main topics: (1) nanometer to subnanometer plasmonic hotspots for SERS; (2) Ångström resolved TERS; (3) chemical mechanisms, i.e., charge-transfer mechanism of SERS and semiconductor-enhanced Raman scattering; and (4) the creation of a strong bridge between the mechanism studies and applications.

摘要

表面增强拉曼散射（SERS）和针尖增强拉曼散射（TERS）开启了众多令人兴奋的研究领域。然而，尽管自这两种技术首次报道以来已提出了大量应用，但尚无一种应用于实际用途。这就需要对SERS和TERS近期的基础及应用研究进行更新。因此，本综述的目标和范围是报告SERS和TERS的新方向与新观点，主要从结合其机理和应用研究的角度出发。关于SERS和TERS的近期进展，本综述讨论了四个主要主题：（1）用于SERS的纳米至亚纳米等离子体热点；（2）埃级分辨的TERS；（3）化学机理，即SERS的电荷转移机理和半导体增强拉曼散射；（4）在机理研究与应用之间建立强有力的桥梁。
