Synthesis of boron-doped diamond with laser heated diamond anvil cell.

Boron-doped diamond has been synthesized from graphite mixed with different ratio of BC at high pressure high temperature (HPHT) using laser heated diamond anvil cell. The starting composition was transformed to diamond compound at pressure ∼9 GPa, 2300-2400 K as indicated by the in-situ X-ray diffraction pattern with synchrotron radiation source. Raman spectrum of the recovered specimen from HPHT state confirmed that boron has been doped into diamond lattice. [ABSTRACT FROM AUTHOR]
