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。

化妆品中成分的相互作用检测方案
One of the major fields of investigation of L'OREAL is to improve the understanding of the chemical composition and structure of skin and hair. To enable a better design of cosmetic products, a thorough understanding of the mechanisms and the nature of the interactions of cosmetic ingredients with these substrates is necessary.Raman is a key analytical method allowing the needed understanding of such mechanisms. In this context,HORIBA Jobin Yvon & L''OREAL Research have established a close collaboration in applying the Raman technique under in vitro conditions or directly in vivo,for hair,skin,nail, eyelashes and model substrates.

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.

石墨烯中拉曼光谱分析检测方案(激光拉曼光谱)
显微拉曼光谱是表征石墨烯上述两种特性的简单可靠方法。拉曼光谱对物质的结构敏感，它的高光谱分辨率和高空间分辨率以及无损分析等特征使其成为石墨烯领域标准而理想的分析工具。　从本文给出的不同样品分析结果可以看出，用拉曼光谱有效表征石墨烯需要光谱仪具有一些特定的性能。高光谱分辨率可以检测到谱峰的微小位移或有效分开 2D 峰以获得石墨烯层数信息。在测试中需要可靠的峰位校正来修正各种潜在的变动影响，确保峰位的准确性。前面已经提过，峰位易受激发波长影响，因此使用不同波长的激光能获取更多的信息。　　另外，需要选择合适的激光强度以避免烧毁样品。拉曼成像有助于定位不同层数的石墨烯片和探测边缘缺陷。新开发出的快速成像方法（SWIFTTM, DuoScanTM）可以有效获取大面积样品图像并且大地节省采集时间。值得关注的是 AFM 和拉曼联用可同时获取石墨烯的结构、机械性能和电性能信息。针尖增强拉曼光谱（TERS）也可用于分析石墨烯的纳米尺度性质以及表征局部缺陷是否存在。

高定向热解石墨中角分辨偏振拉曼检测方案(激光拉曼光谱)
随着低维材料的兴起，样品尺寸往往只有微米量级。实验上已经有多种手段可以实现角分辨偏振拉曼光谱(ARPR)测试，常用的ARPR实验配置是固定入射激光和散射信号的偏振方向，旋转样品。而旋转样品会导致样品点移动，很难实现对微米级样品的原位角分辨拉曼光谱测试。所以重新系统地研究各种ARPR配置的优缺点并且找到对于微米级晶体材料优的实验方法显得十分必要。

含偶氮苯聚合物薄膜中拉曼成像检测方案(激光拉曼光谱)
Raman image (Figure 1) from a thin film of azobenzene-containing polymer thin film (300 nm) that is periodically structured (periodicity of ~1 µm). Raman measurements were recorded with a Labram HR 800 (HORIBA JobinYvon) spectrometer combined with an inverted microscope (Olympus IX 71) and a X,Y Piezoelectric stage to position the sample with the best accuracy and repeatability. A 100X, 0.9 NA microscope objective was used. A Raman spectrum (Fig. 2) was recorded every 100 nm along the X and Y directions with an integration time of 5 seconds per spectrum (λ excitation=752.4 nm). The variation of the Raman signal was integrated over the [10601180]cm-1 spectral domain (Figure 3). It must pointed out that details on the Raman profile are obtained with a spatial resolution better than λ/2 (at the diffraction limit).

Raman spectra, in conjunction with Multivariate (Chemometric) Analysis, have been demonstrated to provide real-time information on the progress of a polymerisation reaction. As shown by this example, these results can provide unexpected information on the details of the reaction. in this case, the inequivalent reaction rates of the two monomers. Such information ultimately enables the process engineer to optimise his process.

地质材料中化学组成检测方案(激光拉曼光谱)
Raman spectroscopy is a practical exploration tool to study geological materials. This technique is a rapid and reliable way to confirm, for example, that a geological sample is really a jade gemstone, or that its composition is dolomite. Chemical information can be obtained without any extraction procedure or sample preparation. Thus, the analysis can be achieved in situ and if necessary directly at the geological site. Raman imaging is also useful to study heterogeneous samples provided by the various fields of application of Earth Science: mineralogy, gemmology, petrology, geoarcheology, paleontology, planetology or volcanology. By the mean of this vibrational technique, the complex history of the Earth can be better understood.

药物中化学组成及分布检测方案(激光拉曼光谱)
The different components of this pharmaceutical sample can be characterized easily by Raman spectroscopy and the comparison with spectra from our libraries allowed us to identify some of these molecules. A good spectral discrimination could be obtained as the characteristic spectral fingerprints have exclusive features. The Raman imaging technique is a very powerful tool as shown here, as it also enables to characterize the spatial distribution of the components with a high spatial resolution. The complementary results obtained by FTIR spectroscopy on the sample confirm the presence of lactose and allows the identification of the third component also observed by Raman spectroscopy. The combination of FTIR and Raman analysis on the same spectrometer represents a powerful analytical tool to readily record both IR and Raman vibrational information from a same sample position.
