“…Figure 11C depicts the excited-state lifetime of single SiV color centers. The controlled shallow implantation of Si ions can allow coupling of SiV color centers with nanoresonators [37][38][39] to further increase the emission rate and make the emission of indistinguishable photons from different quantum emitters at room temperature possible. Some of the emitters show bunching behaviour, indicating the presence of two or more emitting centers below the spatial resolution of the optical system.…”

“…Nonetheless, one could take advantage of nanophotonic structures to strongly enhance the radiative decay rate and thus make these emitters nearly lifetime limited at room temperature. Preliminary studies indicate that the ZPL transition of the SiV can be accelerated by orders of magnitude [39]. For example, Figure 13 shows how a SiV center inside a diamond membrane coupled to a plasmonic gold nanocone can be accelerated by more than four orders of magnitude, hence making the SiV ZPL transition in practice lifetime limited, with direct implications for solid-state quantum optics at room temperatures and for practical applications in quantum information science and technology.…”

Creation of Silicon-Vacancy Color Centers in Diamond by Ion Implantation

Silicon-vacancy (SiV) centers in diamond are gaining an increased interest for application, such as in quantum technologies and sensing. Due to the strong luminescence concentrated in its sharp zero-phonon line at room temperature, SiV centers are being investigated as single-photon sources for quantum communication, and also as temperature probes for sensing. Here, we discussed strategies for the fabrication of SiV centers in diamond based on Si-ion implantation followed by thermal activation. SiV color centers in high-quality single crystals have the best optical properties, but polycrystalline micro and nanostructures are interesting for applications in nano-optics. Moreover, we discuss the photoluminescence properties of SiV centers in phosphorous-doped diamond, which are relevant for the creation of electroluminescent devices, and nanophotonics strategies to improve the emission characteristics of the SiV centers. Finally, the optical properties of such centers at room and high temperatures show the robustness of the center and give perspectives for temperature-sensing applications.

“…Nano-photonic structures, such as solid-immersion lenses [12], nanopillars [13,14], and photonic-crystal cavities [15e17] have shown remarkable improvements in the coupling efficiency and/or the emission rate, but they require advanced nanofabrication tools. Alternatively, color centers in thin diamond membranes would more easily allow to manipulate their radiation pattern for bright directional emission [18,19], the realization of ultrafast singlephoton emission [20], and also, similarly to two-dimensional materials [21], enable hybrid integration into nanophotonics devices, which so far has been mostly pursued using diamond nanocrystals [22,23].…”

“…At first, we investigated the optical properties of SiV centers in PCD membranes of thicknesses from 3 mm down to 55 nm fabricated using MPCVD on a silicon wafer [20]. However, isolating single emitters was limited by the dimensions of the single grains and by the fluorescence background originating from the grain boundaries (GBs).…”

We investigate the optical properties of polycrystalline diamond membranes containing silicon-vacancy (SiV) color centers in combination with other nano-analytical techniques. We analyze the correlation between the Raman signal, the SiV emission, and the background luminescence in the crystalline grains and in the grain boundaries, identifying conditions for the addressability of single SiV centers. Moreover, we perform a scanning transmission electron microscopy (STEM) analysis, which associates the microscopic structure of the membranes and the evolution of the diamond crystals along the growth direction with the photoluminescence properties, as well as a time-of-flight secondary ion mass spectrometry (ToF-SIMS) to address the distribution of Si in implanted and un-implanted membranes. The results of the STEM and ToF-SIMS studies are consistent with the outcome of the optical measurements and provide useful insight into the preparation of polycrystalline samples for quantum nano-optics.

Optical antennas are nanostructures that introduce unprecedented possibilities for light–matter interaction at the nanoscale. An appropriately tailored plasmonic antenna can enhance the total radiative decay rate and modify the angular radiation pattern of a single‐quantum emitter through controlled near‐field coupling. Despite their ability to surpass the fundamental diffraction limit and confine the electromagnetic field to a tiny mode volume, fabricating 3D sharp scanning nanoscale plasmonic structures with desired aspect ratio is yet an ambitious goal. The fabrication of nanocones by gold evaporation on commercial atomic force microscopy probes followed by a focused ion beam milling technique is presented. The method is versatile and allows the fabrication of nanocones with desired dimensions around 100 nm along with an aspect ratio of ≈1. Their optical properties are studied and it is shown how the variation in the refractive index of the dielectric substrate affects the localized surface plasmon resonance of the nanocones, the decay rate enhancement, and the quantum yield of an emitter relevant for fluorescence/Raman scanning experiments. Theoretical studies using finite‐difference time‐domain calculations have guided the fabrication process and are consistent with experimental results.
