Phosphorescence (in the common meaning of the term) seen by naked eye:
No Data
Comments:
Variéty chrome cerussite: SW et LW: Yellowish-White, greenish yellow;
Activator: possibly Ag+ (Gorobets)or Pb2+ (Gaft), accessory Sm3+
Main Activator(s) and spectrum:
Most Common Activator: Pb2+
Other activators: Sm3+ , Eu3+ , Dy3+ , Ag+ ,
Peaks in the spectrum (nm):
(?) : large band peaking at 515 nm,
Sm3+ : peaks at 564, 597, 649nm
Dy3+ : 574, 577nm
Nd3+ : 876, 919nm
Eu3+ : 615, 621, 643, 657, 704nm

Comments on activators and spectra:
Lifetime: 218μs @475nm;
Excitation by CW laser with 532 and 780 nm revealed several luminescence bands and lines. IR lines under 780 nm excitation may be evidently ascribed to Nd3+ and other trivalent REE luminescence present under 532 nm excitation, while the bands origin needs further investigation. (Gaft)
