金刚石中GR1中心的光致发光特性研究

Photoluminescence studies of the neutral vacancy defect known as GR1 centre in diamond

金刚石中空位存在中性、负电及正电三种状态,且空位-空位、空位-杂质之间可以形成更多复合缺陷.利用低温光致发光光谱研究了金刚石经辐照产生的中性空位的发光特性,对进一步研究其他复合缺陷的发光性能提供了重要的指导意义.

The single isolate vacancy in diamond exists in three charged states, neutral, negative and positive; and many complicated defects such as di-vacancies, impurities-vacancy complexes could also be formed in diamond. In this paper, we investigate the optical properties of the irradiation-induced neutral vacancy in diamond by low-temperature micro-photoluminescence technology, which will play a guiding significant role in the further studies of the complex defects in diamond.
