表面增强拉曼散射（Sers）已成功地应用于碳材料的表面表征，如高度取向的热解石墨、热解石墨、玻璃碳、金刚石和碳纤维，通过在碳材料表面蒸镀Ag岛膜。利用电子能量损失谱、X射线光电子能谱和场发射扫描电子显微镜对炭材料的表面化学和形态结构进行了表征。发现碳材料最外表面的拉曼散射被Ag岛膜（50-100 μ m）的存在显著增强。用增强拉曼光谱研究了氩离子刻蚀后石墨和金刚石的化学结构和晶体结构的变化。实验结果表明，银覆盖层表面增强拉曼光谱Sers可以作为一种新型的高灵敏度的表面探针，应用于各种工业材料的表面检测。
Surface-enhanced Raman scattering (SERS) has been successfully applied to the surface characterization of carbon materials such as highly oriented pyrolitic graphite, pyrolitic graphite, glassy carbon, diamond, and carbon fibers by the evaporation of Ag island films onto the surface. The surface chemical and morphological structure of carbon materials has been parallelly characterized by electron energy loss spectroscopy, x-ray photoelectron spectroscopy, and field-emission scanning electron microscope. Raman scattering from the outermost surface of carbon materials is found to be remarkably enhanced by the presence of Ag island films (50–100 Å). The chemical and crystal structure change of graphite and diamond by argon-ion etching has also been studied by the enhanced Raman spectra. The obtained results demonstrate the possibility of using SERS with the Ag overlayer method as a new high-sensitivity surface probe for various kinds of industrial materials.
