No Data
Commentaar:
Fluo brightest under longwave than shortwave contrarly to similar fluorescing calcite;
The previously reported fluorescent Terlinguaite and Corderoite (two mercury minerals) seems to bee both non fluorescent.

Commentaar over activators en spectra:
Synthetic calomel used in chemical lab is also luminescent.Jack De Ment studied the luminescence spectrum of calomel in 1943. It consist of a bright red band extending from 580nm to 640nm under SW excitation.
Activator: "self-activated", the luminescence is produced by electron transfer between paired mercury atoms in different ionization states.
Synthetic calomel used in chemical lab is also luminescent.Jack De Ment studied the luminescence spectrum of calomel in 1943. It consist of a bright red band extending from 580nm to 640nm under SW excitation.
