金刚石中NV心的新红外辐射：塞曼和单轴应力研究
New infrared emission of the NV centre in diamond: Zeeman and uniaxial stress studies
摘要：
在红外线的发射带示出与钻石中的负氮空位中心内的过渡。该带在1046 nm处具有零声子线，单轴应力和磁场测量表明，该发射与1 E和1A 1单重态能级之间的跃迁有关。这些单线态的系统间交叉导致自旋极化，这使得NV-中心对于量子信息处理有吸引力，并且红外发射带提供了在这样的应用中使用中心的新途径。
英文摘要：
An emission band in the infrared is shown to be associated with a transition within the negative nitrogen-vacancy center in diamond. The band has a zero-phonon line at 1046 nm, and uniaxial stress and magnetic field measurements indicate that the emission is associated with a transition between 1E and 1A1 singlet levels. Inter-system crossing to these singlets causes the spin polarisation that makes the NV- centre attractive for quantum information processing, and the infrared emission band provides a new avenue for using the centre in such applications.
