摘要
本文用电子顺磁共振(EPR)方法,研究人造金刚石中氮的电子结构。提出用自旋浓度来表征氯含量的方法,并对不同方法制得的金刚石进行测定。
EPR technique has been used to study the electronic structure of nitrogen impurities in synthesized diamond with pretreated graphite. The observed hyperfine splitting lines of 14N reveals the presence of four types of substitutional nitrogens. A quantitative way has been proposed to estimate the spin concentration of the nitrogen impurities. The analytical result indicates that the spin concentration of nitrogen in diamond synthesized with pretreated graphite is higher than that of synthesized with normal graphite.
