摘　　要：本文利用488 nm及325 nm激光器比较了超纯、氮掺杂及硼掺杂三种金刚石经电子辐照所形成的光学中心.结果表明,金刚石中引入施主或受主原子后,形成了新的光学中心,如NV,DB1中心.After electron irradiation, a large number of interstitial and vacancy-related centres are created in diamond. In this paper, We compare these irradiation-induced centres among ultra pure, nitrogen doped and boron doped crystals by using 488 nm and 325 nm lasers. Results show that some new interesting emissions are observed after the donor or acceptor atoms have been implanted into diamond, such as nitrogen-vacancy complex, DB 1 centre.
