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


No Data

Comments:


Identical to dimethylbenzphenanthrene (Handbook of Mineralogy)

Raman spectroscopy studies indicate that it may be a mixture of complex hydrocarbons including benzonaphthothiophenes (chemical formula: C16H10S) and dinaphthothiophenes (chemical formula: C20H12S)

Approximate abundance of PAHs contained in idrialite from Skaggs Springs (Wise et al. 1986) : picene [40%], chrysene [7%], benzo-phenanthro-thiophene [10%], dibenzo-carbazole [trace], dibenzo-fluorene [33%], indeno-fluorene [7%], and benzo-indeno-fluorene [4%].

Potentially dangerous substance: the PAH contened in Idrialite are toxic.

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.Spectral lines (cm-1): 250, 235, 222, 208;


Best Locality for luminescence(*):
