| contents | As the electroluminescence (EL) of NV color centers in diamond has been realized in p-i-n diodes,the underlying mechanism remains a puzzle for longer than a decade. In this study,using first-principles approaches,the electronic configurations and the possible transitions are comprehensively investigated. Based on the calculated carrier cross sections and transition rates,the mechanism of the EL of NV centers and the charge-state dynamics are revealed. The continuous EL is maintained by the cycle of NV0 ground (GNV0),NV+ metastable (MNV+) and NV0 excited state (ENV0). The weaker EL intensity compared to photoluminescence (PL) is explained by the bottleneck transition from MNV+ to ENV0 and another non-luminescent transition cycle. Additionally,our results also explain the disappearance of the luminescence of NV- as a result of unbalanced transitions between NV- and NV0. This study not only reveal the mechanism of electroluminescence of NV centers and explain experimental observations,but also provide first-principles insights to understand the charge-dynamics of other color centers under electric and optical field. |
