Abstract
The method of hot-filament chemical vapor deposition has been employed to synthesize diamond particles with germanium–vacancy and silicon–vacancy color centers. In the next stage, the reactive ion-plasma etching of the particles was performed. This, yielded diamond nanoparticles with photoluminescence spectra constituted by two narrow high-intensity zero-phonon lines of the centers introduced. These fluorescent diamond nanoparticles are promising for application as sources of double-wave narrow-band emission in luminescent nanothermometry.
