THE GREATEST GUIDE TO COLOR CENTER DIAMOND CRYSTAL

The luminescent Ge-connected composition was prepared by ion implantation of Ge ions into diamond and subsequent annealing or CVD. High purity IIa-form (001) one-crystal diamond substrates (Ingredient 6, Digital grade) have been useful for the ion implantation experiments. The level of nitrogen impurities in the substrate is underneath 5 ppb. Impla
