Phosphorescence (in the common sense of the term) observable with the naked eye:

No data

Triboluminescence: OUI

Comments:

Weloganite from Francon is triboluminescent with a blue flash when scratched (Bill Lechneron Mindat forum)

The white fluorescence seems to be associated with another mineral covering weloganite.

Activator(s) and spectrum:

No data

No spectrum yet

Best localities for fluorescence (*):

Francon Quarry, Montreal, Jacques Cartier County, Québec, Canada;

(*)The data are not exhaustive and are limited to a few remarkable localities for fluorescence
