A variety of Aragonite also known as Mossottite (Luca, 1858)


This variety can contain strontium up to composition (Ca0.5Sr0.5)[CO3]

Main Activator(s) and spectrum:

Most Common Activator: Mn2+

Peaks in the spectrum (nm):

Broad band peaking at 643nm, wave at 710nm

No spectrum for the moment

Comments on activators and spectra:

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 is considered as the principal activator of this red fluorescence.
