ABSTRACT:
Inorganic intercalation phosphors having either the general formula Na.sub.2 (Mg.sub.3-x Tb.sub.x) Al.sub.2 Si.sub.2 O.sub.10 F.sub.2 or Na.sub.2 Mg.sub.3 {(Al.sub.2-x Eu.sub.x)Si}O.sub.10 F.sub.2, were made by doping an inorganic, intercalation, highly charged fluorophlogopite compound having an atomic structure interspersed with vacant spaces with selected activator ions such as terbium or europium capable of luminescent emission when excited by external radiation such as cathode rays.
