Replication data for Optical properties of SiV and GeV color centers in nanodiamonds under hydrostatic pressures up to 180 GPa

We investigate the optical properties of silicon-vacancy (SiV) and germanium-vacancy (GeV) color centers in nanodiamonds under hydrostatic pressure up to 180 GPa. The nanodiamonds were synthetized by Si or Ge-doped plasma assisted chemical vapor deposition and, for our experiment, pressurized in a diamond anvil cell. Data_SiV : replication data for the center wavelength of the photoluminescence of the SiV center as a function of pressure. The file is composed of 4 columns: first is pressure (in GPa), second is error in pressure (in GPa), third is center wavelength (in nm) and fourth is error in center wavelength (in nm). Data_GeV : replication data for the center wavelength of the photoluminescence of the GeV center as a function of pressure. The file is composed of 4 columns: first is pressure (in GPa), second is error in pressure (in GPa), third is center wavelength (in nm) and fourth is error in center wavelength (in nm).
