Abstract

La présente invention concerne un composé à base d'un alcalino-terreux, de soufre et d'aluminium, de gallium ou d'indium, son procédé de préparation et son utilisation comme luminophore. Le composé de l'invention répond à la formule AB2S4 dans laquelle A représente un alcalino-terreux, B l'aluminium, le gallium ou l'indium, et il est caractérisé en ce qu'il se présente sous forme d'une poudre de teneur résiduelle en oxygène d'au plus 1,5 % et constituée de particules de taille moyenne d'au plus 10 .mu.m. Ce composé est obtenu par un procédé qui comporte les étapes suivantes: on forme une solution ou une suspension comprenant des sels des éléments A et B, on sèche par atomisation la solution ou la suspension; on fait réagir le produit obtenu à l'étape précédente avec du sulfure de carbone ou avec un mélange de sulfure d'hydrogène et de sulfure de carbone. Le composé de l'invention peut être utilisé comme luminaphore, notamment en cathodoluminescence.
