Large particle optical properties of synthetic diamond crystals

Cultivation temperature synthetic diamond method using metal diamond crystal solvent if a synthetic diamond as a representative Ni solvent, it may be about 3 mm (15 hours) a small amount of crystalline inclusions, the color is yellow. And if by Fe as solvent, although it can produce colorless crystals, but easy to get skeletal crystal, so Yi Xiang packages containing body. In this case, toabrasive grinding crystal growth rate slow down. Thus we have inclusions Ni solvent inaccessible as a basis to make adding various metals, and in this solvent for crystal cultivation Synthetic diamond. Observed bred various crystal colors. Study to add to the Ni the effect of various metals. In addition to visual observation of endoscopic significant emblem color suits, also measured the absorption spectrum of visible sight.
