Commentaar over activators en spectra:
A specimen from the Nadym River area fluoresces red due to manganese activator. From Mont Saint-Hilaire, crystals have been found that fluoresce intense blue like that of Fluorite under SW, MW, and LW (Jacques Poulin). Also Green luminescence due to U impurities in this locality (pics around 525 nm).
Two different Mn2+ luminescence centers have been found in steady-state spectra of apophyllite: in Ca position with orange luminescence peaking at 600 - 620 nm and in K position with green emission peaking at 500 nm (Tarashchan 1978 cited by Gaft).
