Phosphorescence (in the common sense of the term) observable with the naked eye:

No data

Comments:

In Jakobsberg, Sweden, wolastonite and margarosanite replace barysilite (see picture by Kjell Gatedal in bibliography)

Activator(s) and spectrum:

Activator(s): Mn²⁺ , Pb²⁺,  Ce³⁺,  Nd³⁺,  

Peaks in the spectrum (nm):

Pb²⁺ : broad bands at 325nm (t= 1,2microsec.) and 450nm (t= 10,6microsec.)

Mn²⁺ : broad band at 635nm (t= 540microsec.) (exc. 266nm)

Mn²⁺ : broad band at 635nm (t= 1,2ms) (exc. 355nm)

Mn²⁺ : very large band at 640nm with peak at 630nm (exc. 532nm)

Nd³⁺ : 860, 876, 895nm (exc. 780nm)

No spectrum yet

Comments on spectrum and activators:

Laser-induced time-resolved technique enables to detect two types of Pb²⁺, two types of Mn²⁺ and Ce³⁺ emission centers (Gaft et al. 2013a).

Excitation by CW laser with 532 and 780 nm revealed narrow luminescence lines possibly belonging to Nd³⁺ and broad luminescence band of Mn²⁺
