Fosforescentie (in de algemene betekenis) zien met het blote oog:

No Data


Usually cited as non-fluorescent in the litterature despite pictures and samples in collection; identification to be verified; Fluorescent Hyalite can cover weeksite xls or xls can be included in strong fluorescent chalcedony making difficult to say in some samples if weeksite does fluoresce by itself or not (see sample from Thomas range Mountains, USA on Mindat)


A crystallized sample corresponding to the facies of the weeksite and labelled as such from the Anderson Mine clearly shows a low fluorescence from the crystals themselves (no visible hyalite coating) and a spectrum could even be taken.


Yellowish green fluorescence: RGB: 175, 255, 30 (approximatively calculated from the spectrum)

Activator en spectrum:

Voornaamste Activator: (UO2)2+ (Uranyl ion) intrinsiek

Pieks in het spectrum (nm):

UO22+: 532, 550nm (LW),  511, 531, 553nm (SW)

Commentaar over activators en spectra:

The peaks of the spectrum are not very well defined but there is clearly  a peak around 532nm and a second one at 550nm. Other peaks should be found after deconvolution of the spectrum but are only slightly visible as shoulders in the curve.
