Recently, the nitrogen vacancy (NV) center has emerged as a deterministic single-photon source at room temperature. However, the presence of phonon sideband emission limits the use of NV centers in various quantum optical applications. Here we report a novel way to suppress the phonon sideband emission of NV centers aided with the enhancement of zero phonon line intensity using photonic crystals at room temperature. We study the photonic stop gap mediated charge state conversion in NV centers. The enhancement of phonon sideband emission from the same structures by implementing a different measurement geometry is also discussed. The studies open new avenues in studying the NV center-based quantum nanophotonics and biophotonics.

纳米光子对纳米金刚石色心发射的控制

最近，氮空位（NV）中心已成为室温下确定性的单光子源。但是，声子边带发射的存在限制了NV中心在各种量子光学应用中的使用。在这里，我们报告了一种新颖的方法，该方法通过使用光子晶体在室温下，通过增强零声子线强度来抑制NV中心的声子边带发射。我们研究了在NV中心的光子停止间隙介导的电荷状态转换。还讨论了通过实现不同的测量几何形状来增强来自相同结构的声子边带发射的问题。这些研究为研究基于NV中心的量子纳米光子学和生物光子学开辟了新途径。
