Phosphorescence (in the common meaning of the term) seen by naked eye:
No Data
Comments:
Grains of pure yellow Berzeliite show a red fluorescence under shortwave and no longwave fluorescence. So it is not the fluorescence of calcite through the berzeliite which is seen on shortwave. (?)
It seems that the Berzellite which gives a response under SW is Zn-bearing. The fluorescence color is green under SW. (info: S. Stolze)
Main Activator(s) and spectrum:
No data
Best Locality for luminescence(*):
- Langban, Filipstad, Varmland Province, Sweden (seldom fluorescent in bright blue SW);
(*)Data are not exhaustive and are limited to the most important localities for fluorescence
