| 摘 要： | 金刚石中含有点缺陷、线缺陷、面缺陷、体缺陷四种晶格缺陷类型，但是研究的较多的是点缺陷。点缺陷中产生的缺陷中心对于金刚石的颜色起到重要作用。缺陷中心包括光学活性和不具活性两种。色心就是具有光学活性的缺陷中心。色心主要有两种成因：杂质引起的色心和辐射损伤色心。并且，对于每种色心都有若干个具体的表现形式。不具活性的缺陷中心主要由杂质氢、杂质镍钴引起。本文旨在通过对各种缺陷中心进行小结，为揭示金刚石颜色的成因提供一定依据。 |
| 关 键 词： | 金刚石；缺陷中心；综述；点缺陷；色心；辐射损伤色心 |

| Abstract： | In the diamond,there are four types of lattice defects: the point-defects, the line-defects, the surface-defects and the body-defects. But the study of the point-defects is the dominant. The defect-centers arising in the point-defects play an important role for the color of diamonds. The defect-centers includes two types: optical activity and non-activity. The color-center is a heart defect optical activity of the centre. There are mainly two types of color-centers: color-centers from impurities or from radiation injury. Meantime, each color-center has a number of specific manifestations. The non-activity defects are mainly from the activity of hydrogen impurities, nickel impurities, and cobalt impurities. This paper aims at providing a basis for revealing the cause of the diamond color, through the summary of various defect-centers. |
