Abstract:
Luminescence properties of nitrogen‐vacancy (NV) and silicon‐vacancy (SiV) centers were investigated for the series of O‐terminated composite nanodiamonds consisting of a high‐pressure–high‐temperature (HPHT) diamond core and a chemical‐vapor‐deposition (CVD) diamond outer layer of different thickness. It was found that emission of NV and SiV centers cease to “feel” the diamond surface at a distance of 12 and 4 nm, respectively, from it. This finding determines minimum sizes of O‐terminated nanodiamonds in which stable single photon emitters could be formed based on NV and SiV centers. Suggested composite diamond nanostructure are optimal for design of two‐color luminescent markers. The studied diamond nanoparticles present composite structure of “core‐outer layer” type. The core is 20 nm HPHT diamond containing NV centers, whereas outer diamond layer containing SiV centers is formed by CVD synthesis.
