在过去的30到40年里，各种新型碳材料已被设计用于多种工业用途。现在众所周知，拉曼光谱对结构敏感，即使光谱相当简单。由于拉曼光谱学现在以提供良好的信息而闻名，因此拉曼设备的潜在用户可以请求关于其样品质量的信息。然而，他们往往不能清楚地定义他们所指的“质量”。如果他们正在生长金刚石薄膜，他们可能需要也可能不需要间隙sp2碳来将多晶金刚石粘合在一起。如果他们正在生长坚硬的类金刚石碳（DLC）薄膜，他们可能希望将光谱特性与薄膜的物理特性相关联。在本专栏中，我解释了拉曼特征如何帮助表征碳材料。
In the last 30 to 40 years, various new types of carbon materials have been engineered for multiple industrial uses. It is now well-known that the Raman spectrum is sensitive to the structure, even though the spectrum is rather uncomplicated. Because Raman spectroscopy now has a reputation for providing good information, potential users of Raman equipment can request information on the quality of their sample. However, they are often not able to define clearly what they mean by “quality.” If they are growing diamond films, they may or may not want interstitial sp2 carbon to glue polycrystalline diamond together. If they are growing hard diamond-like carbon (DLC) films, they may want to correlate the spectral characteristics with physical characteristics of the film. In this column, I explain how the Raman characteristics can aid in characterization of carbon materials.
