Phosphorescence (in the common meaning of the term) seen by naked eye:


No Data

Comments:


Chemically identical to Coronene (Hexabenzobenzene), a polycyclic aromatic hydrocarbon used to produce Organic Electroluminescent Material.

The name replaces pendletonite (CNMMN, 1971), karpatite and coronene.

Karpathite is composed of flakes of pure coronene embedded in sedimentary rock. This mineral may result from ancient hydrothermal vent activity. See gallery for a scheme of the chemical structure of coronene.

Beware when manipulating, coronene is toxic and carcinogen:

Comments on activators and spectra:


Blue luminescence due to the two linearly annelated benzene rings characteristic of aromatic compound (singlet-singlet electron transition within the benzene rings).
