Abstract

The formation and thermodynamic stability of silicon-vacancy (Si-V) color centers, intensively emitting at a wavelength of 738 nm, are demonstrated for the first time in nanodiamonds less than 10 nm in size. These findings open prospects for the production of stable and efficient optical nanoemitters (single-photon emitters) based on nanodiamond.
