Mizzonite = variety of MEIONITE (intermediate with MARIALITE and MEIONITE but with predominantly the last one.

Main Activator(s) and spectrum:

Most Common Activator: S2-

Other activators:            Fe3+ , Eu2+ , O-2 ,

Peaks in the spectrum (nm):

Eu2+ repl. Ca2+  : 440nm

Fe3+ repl. Al3+ : red band (band at 710 - 720nm?)

Mn2+ : broad band at 630 - 690nm ?

No spectrum for the moment

Comments on activators and spectra:

Activator: O-2 (Gorobets);


The emission spectrum is dependent upon excitation wavelength, indicating that S2- occupies several different sites.


Gaft reported that the relative efficiency of yellow luminescence from one scapolite sample was increased up to 117 times by heat treatment at 1000 °C for 2 h in air.

The enhancement of yellow luminescence by heat treatment was ascribed to the alteration of SO32- and SO42- to S2-  in scapolite.


Excitation by CW laser at 532 nm revealed several luminescence bands which may be supposedly connected to Mn2+ and Fe3+ centers (Gaft).
