Abstract

The impurity composition of multi-sector plates of nitrogen and boron-containing synthetic HPHT diamonds has been investigated by laser-induced breakdown spectroscopy. It is shown that a comparative analysis of the intensities of the characteristic atomic and molecular bands in the plasma emission spectrum during laser-induced modification of the surface of the samples makes it possible to distinguish both the type of diamond and the crystallographic orientation of the analyzed sector of the sample.

激光诱导表面改性条件下激光诱导击穿光谱法分析合成HPHT金刚石的杂质成分

摘要

通过激光诱导击穿光谱法研究了氮和含硼合成HPHT金刚石多扇区板的杂质组成。结果表明，在对样品表面进行激光诱导的改性过程中，对等离子体发射光谱中的特征原子和分子带的强度进行比较分析，可以区分金刚石的类型和被分析的晶体取向。样本的扇区。
