COLOR CENTER DIAMOND CRYSTAL FUNDAMENTALS EXPLAINED

The spectra are offset for clarity, and the total integrated absorption is identical at both temperatures.Photoluminescence spectroscopy reveals that unstable defects are eliminated by HPHT treatment of Kind IIa brown diamonds to decolorize them. Also, the NV�?NV0 ratio improves to >one in taken care of diamonds (as measured with PL utilizing a 5
