Abstract (en)
[origin: FR2755122A1] The invention concerns a compound with a base of an alkaline-earth, sulphur and aluminium, gallium or indium, method for preparing same and use as luminophore. The compound is of formula AB2S4 in which A represents an alkaline-earth, B aluminium, gallium or indium, and it is characterised in that it is in the form of a powder residual content of oxygen not more than 1.5 % and consists of particles of average size not more than 10 mu m. This compound is obtained by a method consisting in the following steps: forming a solution or a suspension containing salts of elements A and B, drying the solution or suspension by pulverisation; reacting the product obtained from the preceding step with carbon disulphide or with a mixture of hydrogen sulphide and carbon disulphide. The compound can be used as luminophore, in particular in cathodoluminescence.
