基于扫描探针显微镜的近场超空间分辨指纹光谱技术在分子识别及组分鉴别方面具有极大的应用前景.扫描探针显微技术与不同的光谱联合使用,发展出了不同的具有纳米级分辨的指纹光谱技术,其中包括针尖增强拉曼散射光谱技术、纳米级分辨率的傅里叶变换红外光谱技术及散射式的扫描近场太赫兹光谱技术.这三种散射式的扫描近场光学显微技术在实现方式上有所不同,在近场指纹识别方面可以相互补充.该综述主要对三种近场超空间分辨指纹光谱技术的特点进行了深入地分析和比较,并且对这三种技术的研究现状及应用进行了总结.
The near-field and space-resolved fingerprint spectroscopy based on the scanning probe microscope has great application prospect in the molecular recognition and the component identification.The combination of scanning probe microscopy and different spectroscopy has developed different nano- Resolution fingerprinting spectroscopy, including needle-tip enhanced Raman scattering spectroscopy, nanoscale-resolution Fourier transform infrared spectroscopy, and diffuse-scan near-field terahertz spectroscopy. These three scattering-mode scanning near-field optics Microscopy is different in the way of implementation and can complement each other in near-field fingerprinting.This review mainly analyzes and compares the characteristics of three near-field hyperspectral fingerprinting spectroscopy techniques, The research status and application of technology are summarized.
