Commentaar over activators en spectra:

It is generally accepted that the yellow-orange emission of tugtupite with weak vibrational structure at 300 K, which becomes more prominent at low temperatures, is connected to a S₂^-  luminescence center (Povarennykh et al. 1971).

Laser-induced time-resolved technique enables Gaft to detect Eu²⁺ (Band at 430nm) and Ce³⁺ (Band at 360nm), two different Mn²⁺ (Band at 495 & 512nm), Fe3+ (Band at 670nm) and S₂^-  (Band at 603nm) emission centers.
