在金刚石生长时,氮是十分容易进入金刚石的一种杂质。世界各国报道的天然金刚石的氮含量目前一般为0.5原子％,即金刚石每200个原子中有一个氮原子。对于宝石级金刚石来说,一般约为0.1％。就晶体来说这已是很高的杂质含量,因此氮必然地对金刚石的许多性质有深远的影响。它是宝石级金刚石颜色的主要控制剂,例如“卡普”(the cape)金刚石的黄色和“康娜莉”(the canary)金刚石的橙黄色都是由氮所引起的。而且,金刚石在某些技术应用中的价值也决定
Nitrogen is an impurity that is very easy to get into diamond as it grows. The nitrogen content of natural diamond reported by various countries in the world is generally 0.5 at% at present, that is, one nitrogen atom exists in every 200 atoms of diamond. For gem diamonds, it is generally about 0.1%. This is already high impurity content for the crystal, so nitrogen must have profound implications for many properties of diamond. It is the primary control agent for gem-quality diamonds such as yellow of the cape diamond and yellow of the canary diamond, all caused by nitrogen. Moreover, the value of diamond in certain technical applications is also determined
