| Abstract: | 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, DB1 centre. |
