Abstract

a. Procédé de fabrication d'un produit luminescent susceptible d'être excité par un faisceau d'électrons et qui est essentiellement constitué par des cristaux d'oxydes d'yttrium, d'alluminium, de gallium activés par du cerium. b. Ce procédé étant caractérisé en ce qu'on réalise un mélange d'oxyde d'yttrium, d'oxyde d'aluminium, d'oxyde de gallium, d'oxyde de cerium et d'un fluorure minéral qui se décompose pour libérer du fluore à la température de frittage du mélange, et on fritte le mélange pour obtenir un produit ayant une intensité d'émission lumineuse maximale, supérieure à celle que l'on obtient en frittant le mélange sans composé fluoré.at. A method of manufacturing a luminescent product capable of being excited by an electron beam and which consists essentially of crystals of oxides of yttrium, alluminum and gallium activated by cerium. b. This process being characterized in that a mixture of yttrium oxide, aluminum oxide, gallium oxide, cerium oxide and an inorganic fluoride which decomposes to release fluorine is produced. at the sintering temperature of the mixture, and the mixture is sintered to obtain a product having a maximum light emission intensity greater than that obtained by sintering the mixture without fluorinated compound.
