Diamond particles with germanium-vacancy and silicon-vacancy color centers were synthesized by Hot Filament Chemical Vapor Deposition technique. The next step was the reactive ion-plasma etching of the particles. As a result, the diamond nanoparticles were obtained whose photoluminescence spectra consist of two narrow intense zero phonon lines of the embedded centers. Such fluorescent diamond nanoparticles are promising as dual-wavelength narrow-band light emitters for luminescent nanothermometry.
