Comments on activators and spectra:

Shortite was studied by steady-state luminescence spectroscopy and luminescence of trivalent REE, such as Gd, Dy, Sm and Tb was found (Gorobets and Rogojine 2001).
Excitation by CW laser with 532 and 780 nm revealed narrow luminescence lines possibly belonging to Nd3+ and two luminescence bands peaking at 650 and 705 nm
