5 SIMPLE TECHNIQUES FOR COLOR CENTER DIAMOND CRYSTAL

The luminescent Ge-similar structure was geared up by ion implantation of Ge ions into diamond and subsequent annealing or CVD. Higher purity IIa-variety (001) one-crystal diamond substrates (Component six, Digital grade) have been used for the ion implantation experiments. The quantity of nitrogen impurities within the substrate is under five ppb.

诗中“胜美玉”，“过冰清”，写出水晶的质地美，而“亦欲应时明”则描绘出水晶充满灵性的动态美，耐人寻味。罗维是有独特眼光，懂得水晶真谛，第一个称赞水晶超过美玉的伟大诗人。他的认识已被千年之后的科学理论所证实；以水晶为直接吟咏对象的诗篇�
