Phosphorescence (in the common meaning of the term) seen by naked eye:
No Data
Comments:
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+
Best Locality for luminescence(*):
- Langban, Filipstad, Varmland Province, Sweden ;
- Ultevis, Lappland, Sweden ;
