WitrynaThe N3 center is the most common color-producing defect in diamond, consisting of a vacancy surrounded by three nitrogen atoms on a {111} plane. The zero phonon line (ZPL), the identifying emission for N3, occurs at 415 nm. N3 nitrogen center. The N3 center consists of three nitrogen atoms surrounding a vacancy. Its concentration is always just a fraction of the A and B centers. The N3 center is paramagnetic, so its structure is well justified from the analysis of the EPR spectrum P2.
