摘要: 金刚石分类体系经过上百年发展已趋于成熟。以光谱为基础的分类依据是紫外可见近红外光谱(UV-Vis-NIR)和中红外光谱(MIR),主要涉及氮、硼杂质元素,所识别的有关晶格缺陷模型已得到较为合理的解释,但大量的晶格缺陷,包括跟氮有关的晶格缺陷研究尚不透彻,这将限制金刚石应用领域的开拓进程。本文汇集了金刚石紫外-可见光-红外光光谱中呈现的部分吸收特征,特别是对金刚石分类系统进行了完整地说明。除此以外,一些在光谱中较易识别的特征,也已经有了较为合理的理论解释和结构模型,总结汇总这些谱学特征以及其对应的结构模型,可以为金刚石材料的进一步研究和应用提供参考。

Abstract: The “type” of diamond had been developed and trended to perfect in last century. The spectral classification depends on ultraviolet visible near infrared spectrum (UV-Vis-NIR) and mid-infrared spectrum (MIR), mainly relates to nitrogen and boron impurity element. The structure models of nitrogen and boron in each type of diamond have tended to be more plausibility, but an enormous number of lattice defects even related to nitrogen are huge challenge for future work to reach a better understanding. This is an impenetrable wall on the way to explore new application areas for diamond. This article compiles some absorption characteristics in the spectra ranged from ultraviolet, visible light to infrared region. Especially the diamond classification system has been summarized completely. Furthermore, some absorbing features detected in the ultraviolet-visible and infrared spectral lines (UV-Vis-MIR) have been come up with a plausible explanation and/or established somewhat more reasonable structure models. It is very referential collecting these spectral characteristics and their corresponding theoretical models for further research and apply diamond materials.

Key words: diamond, boron, nitrogen, defect model, absorption spectrum
