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

No data

Comments:

Best under LW; Typical from hydrated borate minerals, the crystals of Meyerhofferite are altered probably by deshydratation and a whitish color appears where most of the luminescence is concentrated;

Activator(s) and spectrum:

No spectrum yet

Best localities for fluorescence (*):

• Monte Blanco Mine, Monte Blanco, Black Mts, Amargosa Range, Inyo Co., California, USA;
• Death Valley, Inyo Co., California, USA;

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