Photoluminescence of Germanium-Vacancy Color Centers in Diamond Particles Obtained by Chemical Vapor Deposition

We synthesized diamond particles with germanium-vacancy color centers on a germanium substrate by hot-filament chemical vapor deposition. The formation of color centers occurred during the growth of diamond particles by the introduction of germanium atoms formed by the etching of a crystalline germa...

Description
Summary:We synthesized diamond particles with germanium-vacancy color centers on a germanium substrate by hot-filament chemical vapor deposition. The formation of color centers occurred during the growth of diamond particles by the introduction of germanium atoms formed by the etching of a crystalline germanium wafer with atomic hydrogen. The conditions of the vapor phase deposition, which affect the photoluminescence of germanium-vacancy color centers in diamond particles, are considered. The highest photoluminescence intensity of germanium-vacancy color centers was achieved for diamond particles obtained on a substrate at a temperature of its surface close to the melting point of germanium. In the photoluminescence spectra of diamond particles, we also observed the lines presumably related to optical centers including tu-ngsten.
