    Simplified atomic structure of the NV center. The nitrogen-vacancy center (N-V center or NV center) is one of numerous photoluminescent point defects in diamond.Its most explored and useful properties include its spin-dependent photoluminescence (which enables measurement of the electronic spin state using optically detected magnetic resonance), and its relatively long (millisecond) spin ...

    The most common impurity in diamond is nitrogen, which can comprise up to 1% of a diamond by mass. [13] Previously, all lattice defects in diamond were thought to be the result of structural anomalies; later research revealed nitrogen to be present in most diamonds and in many different configurations.

  4. Optically detected magnetic resonance - Wikipedia

    en.wikipedia.org/wiki/Optically_detected...

    The nitrogen vacancy defect in diamond consists of a single substitutional nitrogen atom (replacing one carbon atom) and an adjacent gap, or vacancy, in the lattice where normally a carbon atom would be located. A nitrogen vacancy centre in the diamond lattice, viewed along the [100] axis. Carbon atoms (grey) make up the bulk diamond crystal.

    In general, organic matter contacting soil has too little nitrogen to support the biosynthetic needs of the decomposing soil microbial population. If the C:N ratio of the decomposing organic matter is above circa 30:1 then the decomposing microbes may absorb nitrogen in mineral form as, e. g., ammonium or nitrates. This mineral nitrogen is said ...

    As it decomposes, the body releases nitrogen and the added natural materials provide carbon. With the cask kept at an optimal temperature, it creates perfect conditions for microbes to break the ...

  7. Nitrogen - Wikipedia

    en.wikipedia.org/wiki/Nitrogen

    Nitrogen is a chemical element; it has symbol N and atomic number 7. Nitrogen is a nonmetal and the lightest member of group 15 of the periodic table, often called the pnictogens. It is a common element in the universe, estimated at seventh in total abundance in the Milky Way and the Solar System.

    If the nitrogen atoms are dispersed throughout the crystal in isolated sites (not paired or grouped), they give the stone an intense yellow or occasionally brown tint (type Ib); the rare canary diamonds belong to this type, which represents only ~0.1% of known natural diamonds. Synthetic diamond containing nitrogen is usually of type Ib.
