NOT KNOWN DETAILS ABOUT COLOR CENTER DIAMOND CRYSTAL

The luminescent Ge-associated framework was geared up by ion implantation of Ge ions into diamond and subsequent annealing or CVD. High purity IIa-type (001) solitary-crystal diamond substrates (Aspect 6, Digital grade) ended up used for the ion implantation experiments. The amount of nitrogen impurities while in the substrate is underneath 5 ppb.
