A synthetic single-crystal diamond that contains nitrogen atoms at a concentration of more than 600 ppm but no more than 1,500 ppm. The nitrogen atoms do not include isolated substitutional nitrogen atoms. L'invention concerne un diamant monocristallin synthétique qui contient des atomes d'azote à une concentration supérieure à 600 ppm mais inférieure ou égale à 1 500 ppm. Les atomes d'azote ne comprennent pas d'atomes d'azote de substitution isolés. 合成単結晶ダイヤモンドは、窒素原子を６００ｐｐｍを超えて、かつ、１５００ｐｐｍ以下の濃度で含有し、前記窒素原子は、孤立置換型窒素原子を含まない。
