Comments on spectrum and activators:

Blue luminescence in catapleite due to TiO6 (Gaft);
Green luminescence due to Uranyl impurities (Typical spectrum);

Cathodoluminescence: light-blue;

Best localities for fluorescence (*):

• Norra Kärr, Gränna, Jönköping, Småland, Sweden;
• Poudrette quarry (Demix quarry), Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec, Canada;
• Khibiny Massif, Kola Peninsula, Murmanskaja Oblast, Northern Region, Russia (only colorless xls are fluorescent SW green);

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