Title (EN) COATED MANGANESE DOPED PHOSPHORS
(FR) LUMINOPHORES DOPÉS AU MANGANÈSE ENROBÉS
Abstract:
(EN) A process for preparing a population of coated phosphor particles is presented. The process inciudes combining particles of a phosphor of formula I: A* [MFy]:Mn4+ with a first solution including a compound of formula II: Ax[MFy¨] to form a suspension, where A is Li, Na, K, Rb, Cs, or a combination thereof; M is Si, Ge, Sn, Ts, Zr, Ai, Ga, In, Sc, Hf, Y, La, Mb, Ta, Bi, Gd, or a combination thereof; x is an absolute value of a charge of the [MFy] ion; and y is 5, 6 or 7. The process further includes combining a second solution Including a source A+ ions with the suspension.
(FR) L'invention concerne un procédé de préparation d'une population de particules de luminophore enrobées. Le procédé consiste à combiner des particules d'un luminophore de formule I : A* [MFy]:Mn4+ avec une première solution comprenant un composé de formule II : Ax[MFy¨] pour former une suspension, A représentant Li, Na, K, Rb, Cs, ou une combinaison de ceux-ci ; M représentant Si, Ge, Sn, Ts, Zr, Ai, Ga, In, Sc, Hf, Y, La, Mb, Ta, Bi, Gd, ou une combinaison de ceux-ci ; x étant une valeur absolue d'une charge de l'ion [MFy] ; et y valant 5, 6 ou 7. Le procédé comprend en outre la combinaison d'une seconde solution comprenant une source d'ions A+ à la suspension.
