AB - Results from PL and Raman spectroscopic analyses of HPHT (high-pressure high-temperature) treated type IIa
diamonds are presented, and these spectral characteristics are compared with those of untreated diamonds of similar color
and type. We identify a number of significant changes by 325 nm He/Cd laser excitation. Several peaks are removed
completely, including H4, H3 system in HPHT treated diamond. The N3 system, however, increased in emission. Also we
can find the behaviour of the nitrogen-vacancy related center N-V centers at 575 and 637.1 nm, as observed with 514 nm
Ar ion laser excitation. When these centers are present, the FWHM (full width at half maximum) of 637.1 nm luminescence
intensities offers a potential means of separating HPHT-treated from untreated typeIIa diamonds. The width of 637.1 nm
(N-V)- line measured at the position of half the peak’s height are determine to range from 19.8 to 32.1 cm-1 for HPHT
treated diamonds.
