| 内容記述 | Negatively charged nitrogen-vacancy (NV?? ) centers in diamond produce a characteristic optical zero-phonon line (ZPL) at 637 nm. This emission line can be observed under optical excitation (i.e. photoluminescence), but is rarely observed under electron excitation (i.e. cathodoluminescence). This study reports that low-temperature (80 K) and low energy (5 keV) cathodoluminescence spectroscopy is able to detect emission peak or spectral dip at the ZPL of NV?? centers. The spectral dip was observed in the diamond samples with high concentration of NV?? centers produced by high-energy (2 MeV) e-beam (EB) irradiation. The effects of EB irradiation fluence, NV?? centers concentration and substitutional nitrogen concentration on the formation of spectral dip were discussed, and a model based on the NV?? absorption of NV0 emission sideband is proposed. |
