Abstract

Surface-enhanced Raman scattering (SERS) is an ultrasensitive detection technique that is used extensively in various analytical applications, including biomedical diagnostics, food safety, and environmental monitoring. Recently, two-dimensional (2D) transition metal dichalcogenides (TMDs) with diverse crystal phases have emerged as promising substrates for SERS detection due to their unique optical and electronic properties. In this perspective, we first introduce the crystal structures and physicochemical properties of TMDs. Then, we briefly summarize the research progress on the preparation of semiconducting and metallic/semi-metallic 2D TMD substrates and their hybrid structures integrated with plasmonic metals for SERS detection. Finally, after we discuss the current challenges and future directions in this exciting field, we highlight the importance of the crystal phases of 2D TMDs in regulating their SERS performance and provide our insights into future research directions in the phase engineering of 2D TMDs for SERS.

二维过渡金属二硫族化合物表面增强拉曼散射的相工程

表面增强拉曼散射（SERS）是一种超灵敏的检测技术，广泛用于各种分析应用，包括生物医学诊断，食品安全和环境监测。近年来，具有不同晶相的二维（2D）过渡金属二硫族化合物（TMDs）由于其独特的光学和电子特性而成为SERS检测的有前途的衬底。在这方面，我们首先介绍了tmd的晶体结构和理化性质。然后，我们简要总结了用于SERS检测的半导体和金属/半金属二维TMD衬底及其与等离子体金属集成的杂化结构的研究进展。最后，在讨论了这一令人兴奋的领域当前的挑战和未来的方向之后，我们强调了二维TMDs的晶体相位在调节其SERS性能中的重要性，并提出了我们对二维TMDs用于SERS的相位工程的未来研究方向的见解。
