When discovered in 1977, surface‐enhanced Raman spectroscopy (SERS) almost immediately became a research phenomenon with dozens of groups on many continents probing this unusual result in which the Raman intensity of a molecule could be increased a millionfold when the molecule is placed on rough silver. Multiple putative explanations were reported that were winnowed down to two major groups: one made reference to the erstwhile nearly unknown entity called the surface plasmon (a collective electronic excitation of metal nanostructures); the other argued that SERS is merely unusually intense resonance Raman. The former was first enunciated by Moskovits in 1978. If indeed plasmonic in nature, one might suppose that SERS would be an effect that requires submicroscopic structure (i.e., nanostructure) and that it would be strongest for the coinage and the alkali metals and accordingly predict that the enhancement (which up to that point had been observed only on electrochemically roughened silver) will also be seen for true silver and gold colloids. All of these predictions were rapidly demonstrated experimentally by many groups, and the plasmonic model for SERS has been developed over the past 40 years into a descriptive, predictive, and quantitative theory that accounts for all of the seminal aspects of SERS.

表面增强拉曼光谱和局域表面等离激元的简要历史，专门用于纪念理查德·范·杜恩（Richard Van Duyne）（1945–2019）

表面增强拉曼光谱（SERS）于1977年被发现时，几乎立即成为一种研究现象，许多大陆上的数十个研究小组都在探索这一不寻常的结果：当将分子置于粗糙表面时，该分子的拉曼强度可以提高一百万倍。银。报道了多种推论性解释，这些解释被归纳为两大类：一类是指以前称为表面等离激元的近乎未知的实体（金属纳米结构的集体电子激发）；另一位辩称，SERS只是拉曼异常强烈的共振。前者于1978年由Moskovits首次提出。如果确实具有等离激元性质，则可能会认为SERS的作用需要亚微观结构（即纳米结构），并且对于造币和碱金属最强，因此可以预测对于真正的银和金胶体，也可以看到这种增强作用（到目前为止，只有在电化学粗糙化的银上才观察到这种增强作用）。所有这些预测已被许多小组迅速地通过实验证明，并且SERS的等离激元模型在过去40年中已发展成为一种描述性，预测性和定量性理论，该理论涵盖了SERS的所有重要方面。
