Abstract: front page image
(EN)Disclosed is an excellent orange or red phosphor which emits a high luminance light and does not decrease much in luminance when exposed to an excitation source. This phosphor contains a crystalline phase having a chemical composition represented by the following general formula [1]. (1 - a - b)(Ln'pMII'1-pMIII'MIV'N3)·a(MIV'(3n+2)/4NnO)·b(AMIV'2N3) [1] In the formula, Ln' represents a metal element selected from lanthanoids, Mn and Ti; MII' represents a divalent metal element other than the Ln' element; MIII' represents a trivalent metal element; MIV' represents a tetravalent metal element; A represents a metal element selected from Li, Na and K; and 0 < p ≤ 0.2, 0 ≤ a, 0 ≤ b, a + b > 0, 0 ≤ n, and 0.002 ≤ (3n + 2)a/4 ≤ 0.9.
(FR)L’invention concerne un excellent luminophore orange ou rouge qui émet une lumière de haute luminance et ne diminue pas beaucoup en termes de luminance lorsqu’il est exposé à une source d'excitation. Ce luminophore contient une phase cristalline ayant une composition chimique représentée par la formule générale [1] suivante. (1 - a - b)(Ln’pMII’1-pMIII’MIV’N3)·a(MIV’(3n+2)/4NnO)·b(AMIV’2N3) [1] Dans la formule, Ln’ représente un élément métallique choisi parmi les lanthanides, Mn et Ti ; MII’ représente un élément métallique divalent différent de l’élément Ln’ ; MIII’ représente un élément métallique trivalent ; MIV’ représente un élément métallique tétravalent ; A représente un élément métallique choisi parmi Li, Na et K ; et 0 < p ≤ 0,2, 0 ≤ a, 0 ≤ b, a + b > 0, 0 ≤ n, et 0,002 ≤ (3n + 2) a/4 ≤ 0,9.
(JA) 高輝度の発光を示し、橙色や赤色の蛍光体として優れ、さらに励起源に曝された場合の輝度の低下が少ない蛍光体は、下記一般式[1]で表される化学組成を有する結晶相を含有する。(1-a-b)(Ln’pII’ 1-pIII’IV’3)・a(MIV’ (3n+2)/4nO)・b(AMIV’ 23)…[1]Ln’はランタノイド、Mn及びTiから選ばれる金属元素、MII’はLn’元素以外の2価の金属元素、MIII’は3価の金属元素、MIV’は4価の金属元素、AはLi、Na、及びKから選ばれる金属元素である。0<p≦0.2、0≦a、0≦b、a+b>0、0≦n、0.002≦(3n+2)a/4≦0.9
