Barium analogue of MARGAROSANITE
Most Common Activator: Mn2+
Other activators: Eu2+ , Nd3+ , Tm3+ ,
Peaks in the spectrum (nm):
Time-resolved luminescence spectra are characterized by Tm3+, Eu2+ and Mn2+ centers (Gaft et al. 2013). Excitation by CW laser with 532 and 785 nm revealed several luminescence bands and lines supposedly connected to Mn2+ and Nd3+
