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/H 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.

对通过固体源同时嵌入发光的吉电子伏特（GeV）和硅空位（SiV）色心的热灯丝化学气相沉积纳米金刚石的研究表明，其零声子线（602和738纳米处）的绝对强度和相对强度均取决于纳米金刚石的生长条件（CH/H气体混合物中的甲烷浓度、生长温度和时间）。结果表明，通过对热灯丝化学气相沉积合成参数的可控选择，可以为定制用于生物系统成像的双色荧光纳米金刚石标记物选择最佳合成条件。
