In the dark pure white phosphorus glows, which explains the name of the element. This greenish glow greatly fascinated the discoverers of the element. The phenomenon phosphorescence has been named after it. Phosphorescence is the slow decay of a metastable electronic state to a lower state under emission of light. The decay is slow because the transition from the excited to the lower state is forbidden, usually because it requires a spin flip. Often it involves a transition from an excited spin-triplet state to a ground state that is a spin-singlet. The metastable excited state may have been populated by thermal excitations or some light source. Since phosphorescence is slow, it persists for some time after the exciting source is removed. It is only natural to assume that the name giver exhibits the phenomenon named after it. However, this is not the case. The glow of pure phosphorus is due to another phenomenon, namely chemiluminescence. This occurs when some product molecules of a chemical ...
