Luminescence, fluorescence and phosphorescence of minerals

EUDIALYTE

Chemical Formula: Na₁₅Ca₆(Fe⁺²,Mn⁺²)₃Zr₃(Si,Nb)(Si₂₅ O₇₃)(O,OH,H₂O)₃(Cl,OH)₂

Familly: Silicates

Status: IMA-A (GP)

Mineral for Display: No

Luminescence:

UV Type	Main color	Intensity	Observation Frequency

Long Waves (365nm):	Orange

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

No Data

Comments:

A favorate of MSH collectors, and not ordinarily thought of as fluorescent. From Alluaiv, Russia a specimen of this manganese zirconium hydroxy silicate is said to be "iron free," and fluoresces orange under LW.

Main Activator(s) and spectrum:

Most Common Activator: Mn²⁺

Other activators: Ti³⁺ ,

Peaks in the spectrum (nm):

Mn²⁺ substituting Ca²⁺ : 590 nm
Ti³⁺ intrins. : 670 nm (Gorobets)

No spectrum for the moment

Best Locality for luminescence(*):

Alluaiv, Russia;

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