VANADINITE

NOT FLUORESCENT but cited by some authors

DOUBTFULL FLUORESCENCE but cited by some authors

Chemical Formula: Pb₅(VO₄)₃Cl

Familly: Phosphates, Arseniates, Vanadates

Status: IMA-GP

Crystal System: Hexagonal

Mineral for Display: No

Luminescence:

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

Comments:

Doubtfull, See ENDLICHITE

Main Activator(s) and spectrum:

Most Common Activator:

Other activators:            Nd³⁺ , VO₄^3- ,

Peaks in the spectrum (nm):

VO₄^3- : broad band at 655nm

Nd³⁺ : 808, 879, 899, 901nm

Comments on activators and spectra:

Vanadinite was studied by steady-state luminescence spectroscopy and luminescence of (VO₄)^3- metal-oxygen complexes was found (Gorobets and Rogojine 2001).

Excitation by CW laser with 532 and 780 nm revealed narrow luminescence lines possibly belonging to Nd³+ and luminescence band similar to ascribed to (VO₄)^3-

Best Locality for luminescence(*):

• Santa Eulalia, Chihuahua, Mexico;
• Ahumada mine, Los Lamentos, Mexico;

(*)Data are not exhaustive and are limited to the most important localities for fluorescence
