论文摘要
我们提出了一个严格的理论模型，用于钻石中的氮 - 呈（NV）中心与等离子金属纳米颗粒（MNP）之间的光学相互作用，并伴随着一个计算有效的程序来解决进化。提出的模型使我们能够在存在和不存在金属纳米颗粒的情况下成功解释NV中心的现有光学排放测量。我们表明，NV-Plasmon相互作用为增强和控制NV中心的光学发射提供了一种多功能的新途径。可以利用MNP类型和大小，NV-MNP中心分离，浸入培养基介电常数和NV方向相对于MNP表面的变化，以改善基于NV中心的纳米电视。
We present a rigorous theoretical model for the optical interaction between a nitrogen-vacancy (NV) centre in diamond and a plasmonic metal nanoparticle (MNP), accompanied by a computationally efficient procedure to solve the evolution. The proposed model enables us to successfully explain existing optical emission measurements of NV centres both in the presence and absence of a metal nanoparticle. We show that the NV-plasmon interaction provides a versatile new avenue to enhance and control the optical emission of an NV centre. Changes to the MNP type and size, NV-MNP centre separation, submerging medium permittivity, and NV orientation with respect to the MNP surface can be exploited to improve a plethora of NV centre based nanodevices.
