本文介绍了一种适合于表面结构研究的激光拉曼光谱原位测试系统,此系统由二个主要部分组成。其一是旋转光束装置,用于避免和减少激光束对所测样品表面的损伤.其二是原位石英拉曼样品池,它可以与气体处理系统连接,对样品进行原位的氧化,还原,反应及抽空等处理.本系统的突出特点是,在改善拉曼谱信噪比的同时,可进行真实状态下的各种原位激光拉曼光谱研究. In this paper, a laser Raman spectroscopy in-situ testing system suitable for the study of surface structure is introduced. The system consists of two main parts. One is a rotating beam device to avoid and reduce the damage of the laser beam to the surface of the sample under test.The second is an in-situ quartz Raman cell, which can be connected to a gas processing system for in-situ oxidation and reduction of the sample , Response and evacuation, etc. The salient feature of this system is that it can be used to study various Raman spectra in situ under the real state while improving the signal-to-noise ratio of Raman spectroscopy.
