Summary: | Disclosed is a complex oxynitride phosphor represented by the formula below, which is obtained by firing a phosphor precursor in the presence of a flux and improved in quantum efficiency and/or durability. M1 xBayM2 zLuOvNw (In the formula, M1 represents at least one activator element selected from the group consisting of Mn, Ce, Pr, Nd, Sm, Eu, Tb, Dy, Ho, Er, Tm and Yb; M2 represents at least one divalent metal element selected from the group consisting of Sr, Ca, Mg and Zn; L represents a metal element selected from group 4 or group 14 metal elements of the periodic table; and 0.00001 = x = 3, 0 = y = 2.99999, 2.6 = x + y + z = 3, 0 < u = 11, 6 < v = 25, and 0 < w = 17.)
L'invention porte sur une matière luminescente d'oxynitrure complexe représentée par la formule ci-après, qui est obtenue par cuisson d'un précurseur de matière luminescente en présence d'un fondant et qui présente un rendement quantique et/ou durabilité améliorés. M1 xBayM2 zLuOvNw (Dans la formule, M1 représente au moins un élément activateur choisi dans le groupe constitué par Mn, Ce, Pr, Nd, Sm, Eu, Tb, Dy, Ho, Er, Tm et Yb; M2 représente au moins un élément de métal divalent choisi dans le groupe constitué par Sr, Ca, Mg et Zn; L représente un élément métallique choisi parmi les éléments métalliques du groupe 4 ou du groupe 14 de la classification périodique; et 0,00001 = x = 3, 0 = y = 2,99999, 2,6 = x + y + z = 3, 0 < u = 11, 6 < v = 25 et 0 < w = 17). |
