Commentaar:
Kunz and Baskerville noted that aragonite fluoresces often strongly during their memorable investigation of 13000 mineral specimens in 1903.
Activator en spectrum:
Voornaamste Activator: Mn2+
Andere activatoren: (UO2)2+ (Uranyl ion) (onzuiverheden) , Onzuiverheden organisch materiaal , Ce3+ , Sm3+ , Eu3+ , Dy3+ , Centra als gevolg van de effecten van straling ,
Pieks in het spectrum (nm):
Sm3+ repl. Ca2+ : 603, 640nm Mn2+ : broad band at 630nm (120nm half-width) Dy3+ : 482, 486, 578, 579nm Radiation induced center : 580nm (very short decay time of approximately 20 ns)

Commentaar over activators en spectra:
Fluo green: due to U in traces; Under cw laser excitation at 532 and 780nm several bands and narrow lines have been found in visible and IR parts of the spectrum. Evidently they may be connected with another type of Mn2+, trivalent REE, such as Sm3+, Eu3+ and different types of Nd3+ centers. The origin of the broad band peaking at approximately 700 nm needs further study. The frequent occurrence of slight amounts of Strontium in aragonite was known during the time of Becquerel and he ascribed the luminescence to the presence of strontium. Later, Nichols confirmed the idea. Hence the name strontioaragonite for some specimen of very bright red fluorescing aragonite. Actually, strontium is not considered anymore as the activator responsable for the red fluorescence of aragonite and Mn and REE are considered as the principal activators of this red fluorescence.
Activators: Mn2+, Sm3+, Dy3+ (Gaft)
The broad luminescence band peaking at 580 nm with very short decay time of approximately 20 ns, could by analogy with Terlingua-type calcite may be preliminarily ascribed to radiation induced luminescence center. (Gaft)
