摘要：

The synthesis of diamond single crystal in the Fe64-Ni36-C system with h-BN additive is investigated at pressure6.5 GPa and temperature range of 1300140℃.The color of the obtained diamond crystals translates from yellow to dark green with increasing the h-BN addition.Fourier-transform infrared（FTIR） results indicate that sp2 hybridization B-N-B and B-N structures generate when the additive content reaches a certain value in the system.The two peaks are located at 745 and 1425 cm-1,respectively Furthermore,the FTIR characteristic peak resulting from nitrogen pairs is noticed and it tends to vanish when the h-BN addition reaches 1.1 wt%.Furthermore,Raman peak of the synthesized diamond shifts down to a lower wavenumber with increasing the h-BN addition content in the synthesis system.
