Abstract:
(EN) The present invention relates to an oxynitride phosphor, a method for preparing the same, and a light-emitting device. More specifically, the present invention provides the oxynitride phosphor including crystals represented by the following formula, a method for preparing the same, and a light-emitting device including the oxynitride phosphor. The invention includes the crystals represented by the following formula to obtain high light-emitting efficiency. [formula] (A(1-p-q)BpCq)aDbSicOdNe: xEu2+, yRe3+, Zq) wherein A, B, and C are different metals, +2 metals; D is metals of group 3; Re 3+ metals; Q is flux; p and q are 0 < p < 1.0 and 0 ≤ q < 1.0; a, b, c, d, and e are 1.0 ≤ a ≤ 2.0, 0 ≤ b ≤ 4.0, 0 < c ≤ 1.0, 0 < d ≤ 1.0, and 0 < e ≤ 2.0; x, y, and z are 0 < x ≤ 0.25, 0 ≤ y ≤ 0.25, and 0 ≤ z ≤ 0.25.
(FR) La présente invention concerne une substance fluorescente à l'oxynitrure, son procédé de préparation, et un dispositif émetteur de lumière. Plus spécifiquement, la présente invention concerne une substance fluorescente à l'oxynitrure comprenant des cristaux représentés par la formule suivante, son procédé de préparation, et un dispositif émetteur de lumière comprenant la substance fluorescente à l'oxynitrure. L'invention inclut les cristaux représentés par la formule suivante pour obtenir un rendement d'émission de lumière élevé. [formule] (A(1-p-q)BpCq)aDbSicOdNe: xEu2+, yRe3+, Zq) où A, B et C sont des métaux différents, +2 des métaux; D est un métal du groupe 3; Re 3+ des métaux; Q est le flux; p et q sont tels que 0 < p < 1,0 et 0 ≤ q < 1,0; a, b, c, d et e sont tels que 1,0 ≤ a ≤ 2,0, 0 ≤ b ≤ 4,0, 0 < c ≤ 1,0, 0 < d ≤ 1,0 et 0 < e ≤ 2,0; x, y et z sont tels que 0 < x ≤ 0,25, 0 ≤ y ≤ 0,25 et 0 ≤ z ≤ 0,25.
