Abstract
<p>We took photoluminescence spectra of 50 typeⅡa natural pink and colorless diamonds, respectively. The measurements were carried out at liquate nitrogen temperature with 488nm and 515nm laser excitation. The FWHM of H3 in pink diamonds with 488nm laser excitation ranged widely from 0.35 to 0.96nm, as compared with the one in colorless diamonds from 0.25 to 0.63nm. 3 pink diamonds of them exhibited over 0.70, which had a remarkable 535.8nm peak with 515nm laser excitation.</p>
