为了使金刚石薄膜作为各种用途的有价值的工程材料得到优化，需要开发强有力的方法对其进行表征。在使用的许多方法中，拉曼显微镜可能是最有价值的，因为它提供了每种不同形式的碳(例如钻石、石墨、巴克球)的容易区分的特征。此外，它是非破坏性的，几乎不需要样品准备，在空气中进行，并可以生成样品中不同形式碳的空间分辨率地图。本文首先回顾了用于分析金刚石和金刚石薄膜的拉曼技术的优点(和一些缺陷)，并概述了一些最新的发展(例如，表面增强拉曼光谱和紫外拉曼光谱)，这些进展有望提供更深入的了解这些材料的杰出性能。本文的其余部分将致力于拉曼光谱在钻石科学和技术中的应用。涵盖的主题包括使用拉曼光谱评估应力、晶体完整性、相纯度、微晶尺寸、点缺陷以及钻石和钻石薄膜中的掺杂。
The optimization of diamond films as valuable engineering materials for a wide variety of applications has required the development of robust methods for their characterization. Of the many methods used, Raman microscopy is perhaps the most valuable because it provides readily distinguishable signatures of each of the different forms of carbon (e.g. diamond, graphite, buckyballs). In addition it is nondestructive, requires little or no specimen preparation, is performed in air and can produce spatially resolved maps of the different forms of carbon within a specimen. This article begins by reviewing the strengths (and some of the pitfalls) of the Raman technique for the analysis of diamond and diamond films and surveys some of the latest developments (for example, surface-enhanced Raman and ultraviolet Raman spectroscopy) which hold the promise of providing a more profound understanding of the outstanding properties of these materials. The remainder of the article is devoted to the uses of Raman spectroscopy in diamond science and technology. Topics covered include using Raman spectroscopy to assess stress, crystalline perfection, phase purity, crystallite size, point defects and doping in diamond and diamond films.
