石墨烯中表征和改性研究检测方案(激光拉曼光谱)
拉曼光谱已经成为石墨烯的表征和改性研究中必不可少的工具，在石墨烯的层数、缺陷表征，以及掺杂、堆叠、层间嵌入、环境影响等方面的研究起着非常重要的作用。拉曼成像不仅可直观的表征不同层石墨烯层数的空间分布，还可以表征石墨烯掺杂、形变引起的拉曼峰位、峰形变化的分布。

爆炸物的直接拉曼成像研究
显微拉曼分析已经成为表面分析和固相颗粒分析中一项常规必备的实验手段。新的自动化技术已经使得分析人员可以方便地研究表面污染物，分析表面结构。刑事侦查领域以及司法部门的研究人员对于核实某一表面上的爆炸物存在特别感兴趣，他们也关注于研究某种成分在爆炸物或易爆材料中的分布情况。以前，用来提供此类信息的手段有有损伤性的色谱法、质谱法；还有AFM之类定性分析方法。然而，这些分析技术或者对样品是破坏性的，并且需要冗长的样品提纯过程，或者对样品特征的揭示很少，并且是间接性的表征。比较而言，拉曼显微技术可以提供无损的、原位的、详细的特征光谱和分布信息。本文报道了如何利用显微拉曼对含有两种典型成分三次甲基三硝基胺（RDX）和季戊四醇四硝酸酯（PETN）的某种爆炸物在表面上的存在进行表征。

Derivation of Physical Parameters from Raman Spectra
The Raman spectra of elemental carbon materials are known to be sensitive to polymorphy. For hard carbon films, the spectra of amorphous and diamond-like carbons can be band-fit to separate the contributions of the "graphitic carbon" (G band) from the "disordered carbon" (D band). The spectral behaviour of carbon films has been empirically correlated with thin film physical properties such as hardness, durability, optical transparency, electrical conductivity, thermal conductivity and corrosion resistance, and can be of use for prediction of these properties without extensive alternative testing.

Analysis Solid State Chemical Reactions
Composite materials are, by definition, multi-phased. Quite often these phases are not distinguishable by optical microscopy. Raman analysis provides very rapid analysis that can differentiate phases, even closely related phases such as polymorphs of a given composition, or differing stoichiometries in a solid system. Recently a SiC conversion coating on a carbon-carbon composite used in the space shuttle was analyzed and various phases were mapped. The identification of phases, in combination with maps showing the physical proximity of the phases, provide insight into the solid state chemical reactions that produce the multi-phase coating.

PCI3， PCI5中反应监控检测方案(激光拉曼光谱)
Dispersive Raman spectroscopy is successfully applied to this process application. The system quickly and clearly monitors the reaction. This insures safer and more efficient formation of the desired product. The technique also guides the process shut-down for maintenance without any additional hardware. In this application the dispersive Raman spectroscopy technique returns higher quality data in less time and with less laser power than FT methods.
