Abstract There are a few studies reported in the literature describing the conversion of intrinsic defects but the involvement of nitrogen-interstitials in diamond has not been reported so far. In this paper, a detailed study on the conversion of nitrogen-interstitials in diamond during the irradiation and further annealing were presented by the micro-photoluminescence spectra. The results indicated that the interstitials were immobile until 300 °C and then escaped from the nitrogen capture, followed by migration and recombination with vacancies in the structure of nitrogen-vacancy and vacancy centers.

电子辐照金刚石中氮填隙缺陷的光致发光和退火

摘要 文献中报道了一些描述固有缺陷转化的研究，但迄今为止还没有报道过氮填隙物在金刚石中的参与。在本文中，通过微光致发光光谱详细研究了在辐照和进一步退火过程中金刚石中氮填隙物的转化。结果表明，间隙分子在 300 °C 之前是固定的，然后从氮捕获中逸出，随后迁移并与氮空位和空位中心结构中的空位复合。
