Comments on spectrum and activators:

Kunz and Baskerville studied the emission of chlorophane in 1903. Some specimens from the Long Hill district, Trumbull, Connec., USA, was found by K. H. Roll (1944) to exhibit thermoluminescence, thermophosphorescence, triboluminescence and fluorescence! (see De Ment in bibliography).

Yttrium and Ytterbium are suspected as activators (De Ment 1947).

Best localities for fluorescence (*):

• Blue Bird Mine, Cochise County, Arizona, USA;
• Petaca District, Rio Arriba Co., New Mexico, USA;
• Long Hill district, Trumbull, Connec., USA;

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