Phosphorescence (in the common sense of the term) observable with the naked eye:

No data

Activator(s) and spectrum:

Activator(s): S₂^-, 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 

No spectrum yet

Comments on spectrum and activators:

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).
