Title: Fluorescent and cathodoluminescent phophors structurally related to sodalite

Abstract

Blue, quantum-confined phosphors for field-emission displays made by reducing metal (M) sulfoaluminates at high temperature. This yields phases of the type M.sub.4 (AlO.sub.2).sub.6 S. Bulk sulfide contaminant mixed with the reduced sulfoaluminate phase is removed by treating it with a chelating agent in nonaqueous solution. A photometric cathodoluminescence efficiency of 9 lumen/watt at 1000 V for Sr.sub.3 PbS(AlO.sub.2).sub.6 is observed. Undoped Sr.sub.4 S(AlO).sub.6 displays 5 lumen/watt at 1000 V, with excellent blue chromatic saturation.
