Comments on activators and spectra:

Under lamps excitation tourmaline is practically non-luminescent, while under X-ray excitation it exhibits impurity luminescence from Fe3+ centered at 700–750 nm and Mn2+ centered at 560–570 nm (Kusnetsov and Tarashchan 1988). (Gaft)


Activators: Cr3+ (lines at 691, 697, 707 nm), Fe3+ (band at 720 - 750 nm), Mn2+ (band at 560 - 570 nm)
