NOT KNOWN DETAILS ABOUT COLOR CENTER DIAMOND CRYSTAL

The luminescent Ge-similar construction was ready by ion implantation of Ge ions into diamond and subsequent annealing or CVD. Higher purity IIa-sort (001) single-crystal diamond substrates (Factor six, electronic grade) were being used for the ion implantation experiments. The amount of nitrogen impurities in the substrate is down below 5 ppb. Imp
