Database of luminescent Minerals


NOT FLUORESCENT but cited by some authors

Chemical Formula: Fe+2(UO2)2(PO4)2 8H2O

Familly: Phosphates, Arseniates, Vanadates

Status: IMA-GP

Mineral for Display: No


UV Type Main color Intensity Observation Frequency

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

No Data


Microscopic and microprobe study of polished sections resulted in identification of the supposed bassetite of the Jáchymov (Joachimsthal) ore district as a mixture of meta-autunite and amorphous Fe-hydroxides, which replaced the original U-mica. The pseudomorphs fluoresce mottled yellow in ultraviolet light. (see bibliography).But Bassetite itself is non-fluorescent.

Main Activator(s) and spectrum:

Most Common Activator: (UO2)2+ (Uranyl ion) intrinsic

Other activators:            ,

No spectrum for the moment

Best Locality for luminescence(*):
