Duo Emission of CVD Nanodiamonds Doped by SiV and GeV Color Centers: Effects of Growth Conditions

The investigation of the hot filament chemical vapor deposition nanodiamonds with simultaneously embedded luminescent GeV(−) and SiV(−) color centers from solid sources showed that both the absolute and relative intensities of their zero-phonon lines (at 602 and 738 nm) depend on nanodiamond growth...

Descripción
Sumario:The investigation of the hot filament chemical vapor deposition nanodiamonds with simultaneously embedded luminescent GeV(−) and SiV(−) color centers from solid sources showed that both the absolute and relative intensities of their zero-phonon lines (at 602 and 738 nm) depend on nanodiamond growth conditions (a methane concentration in the CH(4)/H(2) gas mixture, growth temperature, and time). It is shown that a controlled choice of parameters of hot filament chemical vapor deposition synthesis makes it possible to select the optimal synthesis conditions for tailoring bicolor fluorescence nanodiamond labels for imaging biological systems.
