论文摘要
化学蒸气沉积（CVD）生长钻石中氮气接种中心（NV中心）的电子旋转形成了磁场和温度的理想探针，以及用于量子信息处理的有希望的Qu-lits。因此，研究和控制在如此高纯度晶体中NV中心的磁环境对于这些应用至关重要。我们在CVD生长的钻石中证明了顺磁性物种的光学检测，例如与氢相关的复合物。 NV中心对这些物种的电子自旋的共振转移通过沿[100]晶体方向使用磁场扫描，从而在NV光致发光中产生明显的特征。我们的结果为CVD生长过程的更详细研究以及对新型超极化顺磁性物种的旋转的相干控制提供了前景。
The electronic spins of the nitrogen-vacancy centers (NV centers) in Chemical-Vapor-Deposition (CVD) grown diamonds form ideal probes of magnetic fields and temperature, as well as promising qu-bits for quantum information processing. Studying and controlling the magnetic environment of NV centers in such high purity crystals is thus essential for these applications. We demonstrate optical detection of paramagnetic species, such as hydrogen-related complexes, in a CVD-grown diamond. The resonant transfer of the NV centers' polarized electronic spins to the electronic spins of these species generates conspicuous features in the NV photoluminescence by employing magnetic field scans along the [100] crystal direction. Our results offer prospects for more detailed studies of CVD-grown processes as well as for coherent control of the spin of novel classes of hyper-polarized paramagnetic species.
