Phosphorescence (in the common meaning of the term) seen by naked eye:
No Data
Comments:
Specimens of halite from Inowroclaw, Poland, have appeared on the market with a fluorescence in a beautiful bright yellow-orange under SW. This respose is very unusual since halite usually fluoresces orange-red, including fine crystal specimens from Inowroclaw.

Most Common Activator: Mn2+
Peaks in the spectrum (nm):
Mn2+ repl. Na+ with Pb as co-activator : 590nm (band)
Mn2+ interstition : 630 nm (band)
