Comments on activators and spectra:

Phenakite was studied by steady-state luminescence spectroscopy and supposedly Fe3+ emission was found (Gorobets and Rogojine 2001).

Excitation by CW laser with 532 and 780 nm revealed several luminescence lines which may be evidently ascribed to Nd3+ and band peaking at 670 nm of unknown origin.


Phenacite (containing Be) and willemite (containing Zn) are isostructural and can be mixed in composition. Mn as activator gives orange-red luminescent color.

Russian scientist demonstrated that trivalent Fe could give the pure red luminescent color for phenacite like in Madagascar samples and in feldspar.
