Figure 6
Integrated spectra of rhombohedral boron nitride (r-BN). (a) r-BN and the pressure medium at 5 GPa and 2473 K; (b) only the pressure medium close to the sample; (c) final spectrum of the sample after subtraction of the sample environment. The corresponding images were collected in 30 s using 55.5 keV radiation. Miller indices (hkl) of the r-BN sample and h-BN impurities are indicated. |
