金刚石中的NV中心与等离子体金属纳米颗粒的光学相互作用

Optical interaction of the NV- centre in diamond with a plasmonic metal nanoparticle

Harini Hapuarachchi, Francesco Campaioli, Jared H. Cole

摘要:

我们提出了一个严格的理论模型,金刚石中的氮空位(NV)中心和等离子体金属纳米颗粒(MNP)之间的光学相互作用,伴随着一个计算效率高的程序来解决的演变。所提出的模型使我们能够成功地解释现有的光学发射测量的NV中心在存在和不存在的金属纳米粒子。我们表明,NV等离子体相互作用提供了一个多功能的新途径,以提高和控制的NV中心的光发射。可以利用MNP类型和尺寸、NV-MNP中心分离、浸没介质介电常数和NV相对于MNP表面的取向的改变来改进过多的基于NV中心的纳米器件。

英文摘要:

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.
