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.
