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.
Key words: diamond; defect-center; review; point-defect; color-center; color-center from radiation injury
