Comments on activators and spectra:
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 Locality for luminescence(*):

- Long Hill district, Trumbull, Connec., USA;
(*)Data are not exhaustive and are limited to the most important localities for fluorescence
