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

No Data


Specimens of halite from Inowroclaw, Poland, have appeared on the market an fluoresce 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.

Main Activator(s) and spectrum:

Most Common Activator: Mn2+

Peaks in the spectrum (nm):

Mn2+ repl. Na  : 590nm (band)

Mn2+ interstition : 630 nm (band)

Comments on activators and spectra:

Activator for red: Mn2+ with Pb as co-activator. Color (more orange or more red depends of Mn concentration).
