5 SIMPLE TECHNIQUES FOR COLOR CENTER DIAMOND CRYSTAL

The spectra happen to be offset for clarity, and the total built-in absorption is similar at both equally temperatures.Photoluminescence spectroscopy reveals that unstable defects are eradicated by HPHT treatment method of Form IIa brown diamonds to decolorize them. Furthermore, the NV�?NV0 ratio improves to >one in treated diamonds (as calculate
