Commentaar over activators en spectra:
Strontianite has been studied by steady-state luminescence spectroscopy and trivalent REE, such as Dy, Sm, Nd and Ce, were found together with Mn2+ and uranyl (Gorobets and Rogojine 2001).
Luminescence characterized by broad bands associated with absoption of water-organic complexes (Tarashchan in Gaft).
Also possibly Pb2+ (Gaft);
O-2 (Gorobets);
