Abstract

Una pantalla luminiscente perfeccionada que comprende un sustrato provisto con un aluminato luminiscente ternario con estructura cristalina hexagonal, relacionada con la estructura del magnetoplumbito, caracterizada por que el aluminato comprende gadolinio y es activado por uno al menos de los elementos Pb, Sb, Ce, Sn, Tb, Mn, Cr y Dv, y porque la composición del aluminato puede ser representada en un diagrama de fases ternario ABC, en donde A representa 1/2d2O3 y por lo menos uno de los óxidos 1/2La2O3, 1/2Ce2O3, 1/2Tb2O3, 1/2Dy2O3, 1/2Sb2O3, PbO y SnO.
