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

No data

Comments:

Sometime intimately associated with margarosanite in Franklin; the margarosanite could therefore be responsible for the blue luminescence.
Other locality: Andover

Activator(s) and spectrum:

Activator(s): Fe³⁺,

No spectrum yet

Comments on spectrum and activators:

Hyalophane is a baryum feldspar close to MICROCLINE and amazonite; the red luminescence could therefore be due to Fe³⁺ as in those minerals.
The blue fluorescence could be associated to Pb as activator. 

Best localities for fluorescence (*):

• Jakobsberg Mine, Jakobsberg ore field, Nordmark district, Filipstad, Värmland, Sweden (Blue SW);
• Old Mill Site, Franklin, Franklin Mining District, Sussex Co., New Jersey, USA (fluo red SW);
• Franklin Mine, Franklin, Franklin Mining District, Sussex Co., New Jersey, USA (blue fluo SW due to inclusions of margarosanite? and also Pale red SW);
• Langban, Filipstad, Varmland Province, Sweden;
• Zagradski Potok Mine, Zagradski Creek, Busovača, Central Bosnia Canton, Federation of Bosnia and Herzegovina, Bosnia and Herzegovina (weak red SW);

(*)The data are not exhaustive and are limited to a few remarkable localities for fluorescence
