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

No Data


Associated with dull red fluorescing tilasite in Langban.

Main Activator(s) and spectrum:

Most Common Activator: Mn2+

Other activators:            Nd3+ ,

Peaks in the spectrum (nm):

Mn2+ repl. Ca2+  : band peaking at 585 - 612nm

Nd3+ : 874nm (exc. 780nm)

No spectrum for the moment

Comments on activators and spectra:

Svabite was studied by steady-state luminescence spectroscopy and luminescence of Mn2+ was found (Gorobets and Rogojine 2001).

Excitation by CW laser with 532 and 780 nm revealed band of Mn2+ and narrow luminescence lines of evidently Nd3+
