Phosphorescence (in the common meaning of the term) seen by naked eye:
No Data
Comments:
In Jakobsberg, Sweden, wolastonite and margarosanite replace barysilite (see picture by Kjell Gatedal in bibliography)
Main Activator(s) and spectrum:
Most Common Activator: Mn2+
Other activators: Pb2+ , Ce3+ , Nd3+ ,
Peaks in the spectrum (nm):
Pb2+ : broad bands at 325nm (t= 1,2microsec.) and 450nm (t= 10,6microsec.)
Mn2+ : broad band at 635nm (t= 540microsec.) (exc. 266nm)
Mn2+ : broad band at 635nm (t= 1,2ms) (exc. 355nm)
Mn2+ : very large band at 640nm with peak at 630nm (exc. 532nm)
Nd3+ : 860, 876, 895nm (exc. 780nm)
No spectrum for the moment
Comments on activators and spectra:
Laser-induced time-resolved technique enables to detect two types of Pb2+, two types of Mn2+ and Ce3+ emission centers (Gaft et al. 2013a).
Excitation by CW laser with 532 and 780 nm revealed narrow luminescence lines possibly belonging to Nd3+ and broad luminescence band of Mn2+
