Title
(EN) NITRIDE PHOSPHORS WITH INTERSTITIAL CATIONS FOR CHARGE BALANCE
(FR) SUBSTANCES LUMINESCENTES À BASE DE NITRURES COMPRENANT DES CATIONS INTERSTITIELS POUR LE BILAN IONIQUE
Abstract
(EN) Phosphors comprising a nitride-based composition represented by the chemical formula: M(x/v)(M'aM"b)Si(c-x)A1xNd :RE, wherein: M is a divalent or trivalent metal with valence v; M' is at least one divalent metal; M" is at least one trivalent metal; 2a + 3b + 4c = 3d; and RE is at least one element selected from the group consisting of Eu, Ce, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, Tm, Yb. Furthermore, the nitride-based composition may have the general crystalline structure of M'aM"bSicNd, where A1 substitutes for Si within the crystalline structure and M is located within the crystalline structure substantially at the interstitial sites.
(FR) La présente invention concerne des substances luminescentes comprenant une composition à base de nitrures représentée par la formule chimique suivante : M(x/v)(M'aM"b)Si(c-x)A1xNd :RE, dans laquelle : M représente un métal divalent ou trivalent de valence v ; M' représente au moins un métal divalent ; M" représente au moins un métal trivalent ; 2a + 3b + 4c = 3d ; et RE représente au moins un élément choisi dans le groupe comprenant Eu, Ce, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, Tm, Yb. De plus, la composition à base de nitrures selon l'invention peut avoir la structure cristalline générale de M'aM"bSicNd, dans laquelle A1 se substitue à Si au sein de la structure cristalline et M est situé à l'intérieur de la structure cristalline en grande partie au niveau des sites interstitiels.
