Phosphorescence (in the common meaning of the term) seen by naked eye:
No Data
Main Activator(s) and spectrum:
Most Common Activator: S2-
Other activators: Fe3+ ,
Peaks in the spectrum (nm):
S2- : very broad band peaking at 603nm with weak vibrational structure Fe3+ : red large band peaking at 725 nm with very long decay time
Comments on activators and spectra:
Laser induced time-resolved luminescence spectra of analcime revealed slightly structured orange band peaking at 603 nm with very short decay time evidently belonging to S2- , red band peaking at 725 nm with very long decay time evidently belonging to Fe3+ and blue band peaking at 450 nm with short decay time with unknown origin (Gaft).
