Abstract: front page image
(EN)A fluorophor comprising, as a main component, an &agr; type sialon crystal which contains at least A element (wherein A represents one or more elements selected from among Mn, Ce, Pr, Nd, Sm, Eu, Tb, Dy, Er, Tm and Yb), M element (wherein M represents one or more elements selected from among Li, Na, Mg, Ca, Y, La, Gd and Lu), Si, Al, oxygen and nitrogen, and is represented by the general formulae: (Mx, Ay)(Si12-(m+n)Alm+n)(OnN16-n) (1) m = &dgr;M×x + &dgr;A×y (2) 0.2 ≤ x ≤ 2.4 (3) 0.001 ≤ y ≤ 0.4 (4) and 0.5×m < n ≤ 4 (5). The fluorophor is reduced in the lowering of brightness, and is useful for a white LED and the like.
(FR)La présente invention concerne un fluorophore qui comprend, en tant que composant principal, un cristal de sialon de type &agr; qui contient au moins un élément A (A représentant un ou plusieurs éléments choisis parmi Mn, Ce, Pr, Nd, Sm, Eu, Tb, Dy, Er, Tm et Yb), un élément M (M représentant un ou plusieurs éléments choisis parmi Li, Na, Mg, Ca, Y, La, Gd et Lu), Si, Al, de l'oxygène et de l'azote, et qui est représenté par les formules générales : (Mx, Ay)(Si12-(m+n)Alm+n)(OnN16-n) (1) m = &dgr;M×x + &dgr;A×y (2) 0,2 ≤ x ≤ 2,4 (3) 0,001 ≤ y ≤ 0,4 (4) et 0,5×m < n ≤ 4 (5). Le fluorophore présente un abaissement de la luminosité réduit et il peut être utilisé en tant que LED blanche et dans des utilisations similaires.
