三、发AM/JACS,做二维材料:Raman资料整理+进阶拉曼教程

拉曼光谱作为一种散射光谱，基于印度科学家C.V.拉曼发现的拉曼散射效应：不同的入射光频率的散射光谱进行分析，从而得到分子振动、转动的信息，并应用于分子结构分析研究。拉曼光谱仪一般由光源、外光路、色散系统及信息处理与显示系统五部分组成。激光Raman光谱仪与傅立叶变换-Raman光谱仪是常见的两种类型，激光Raman光谱仪因其与红外光谱相同的波长范围和相对简单的操作而备受重视。

激光Raman光谱仪以He-Ne激光器或Ar激光器作为光源，波长为632.8nm或514.5nm、488.0nm。散射强度与光的频率成反比，使用光栅或多单色器作为单色器，光电倍增管或光子计数器作为检测器。优点包括：光源频率可调、分辨率高、谱峰常为尖峰、样品用量少、测试范围广涵盖水溶液样品。然而，激光Raman光谱仪容易受到荧光的干扰，为此开发了新型的傅里叶变换近红外激光拉曼光谱仪和共焦激光光谱仪。

傅立叶变换-Raman光谱仪使用Nd-YAG钇铝石榴石激光器作为光源，高灵敏度的铟镓砷探头作为检测器。由激光光源、试样室、迈克尔逊干涉仪、特殊滤光器和检测器组成。优点包括避免荧光干扰、精度高、测试速度快。

激光Raman光谱仪与傅立叶变换-Raman光谱仪的主要区别在于光源、试样室、检测器和所采用的技术，以及它们的优缺点。激光Raman光谱仪操作相对简单，而傅立叶变换-Raman光谱仪则提供了更高的精度和更快的测试速度。然而，拉曼光谱仪也有其局限性，如拉曼散射面积的限制、不同振动峰的重叠、拉曼散射强度的光学系统参数影响、荧光现象的干扰、曲线非线性问题、对被测体体系带来的污染等。

拉曼检测的优点包括：光谱范围广泛，覆盖6000cm-1至50 cm-1，可以发现红外光谱难以探索的物质信息；无损无接触分析和鉴别各类天然和人工合成毒品；分析包埋在透明样品内部的异物和杂质；无损分析现场提取的亚微米尺寸的微量痕迹样品；利用共聚焦拉曼成像轻松获取交叉笔画或印刷的前后顺序信息；无需样品处理，可以非接触测样，实现检测过程对样品零损耗；水峰对拉曼光谱的干扰小，可以轻松测试水溶液样品。

在科研领域，拉曼光谱是一种强大的工具，提供了快速、简单、可重复且无损伤的定性定量分析。通过关注公众号科学指南针-测试万事屋，后台回复“2021拉曼”，可以获得拉曼视频操作技巧、拉曼软件、拉曼光谱原理及应用、拉曼光谱有关书籍及文章、拉曼光谱基础及使用过程、拉曼光谱分析、拉曼光谱常见问题集锦、拉曼光谱测试及应用等详细资料，快速开启拉曼光谱进阶之路。
