As the light source is suitable in particular a lamp (especially fluorescent light) or an LED (light emitting diode) which produces, for example, white light.

Stand der Technik State of the art

Aus der WO 98/05078 ist bereits ein Leuchtstoff für Lichtquellen und zugehörige Lichtquelle bekannt. From WO 98/05078 a phosphor for light sources and associated light source is already known. Als Leuchtstoff wird dort ein Granat der Struktur A 3 B 5 O 12 einge setzt, dessen Wirtsgitter als erste Komponente A aus mindestens einer der Seltenen Erdmetalle Y, Lu, Sc, La, Gd oder Sm besteht. A garnet structure A 3 B 5 O 12 is inserted there is, the host lattice is composed as a first component A consisting of at least one of the rare earth metals Y, Lu, Sc, La, Gd or Sm as a phosphor. Weiter wird für die zweite Kompo nente B eines der Elemente Al, Ca oder In verwendet. Next component B one of the elements Al, Ca, or In is used for the second Comp. Als Dotierstoff wird aus schließlich Ce eingesetzt. As a dopant is used in finally Ce.

Aus der WO 97/50132 ist ein sehr ähnlicher Leuchtstoff bekannt. From WO 97/50132 a very similar phosphor is known. Als Dotierstoff wird dort entweder Ce oder Tb eingesetzt. either Ce or Tb is there used as a dopant. Während Ce im gelben Spektralbereich emit tiert, liegt die Emission des Tb im grünen Spektralbereich. While Ce advantage emit in the yellow spectral emission of Tb in the green spectral range. In beiden Fällen wird das Prinzip der Komplementärfarbe (blau emittierende Lichtquelle und gelb emittieren der Leuchtstoff) zur Erzielung einer weißen Lichtfarbe verwendet. In both cases, the principle of the complementary color (blue-emitting light source and yellow the phosphor emit) to obtain a white light color used.

Schließlich ist in EP-A 124 175 eine Leuchtstofflampe beschrieben, die neben einer Quecksilberfüllung mehrere Leuchtstoffe enthält. Finally, in EP-A 124 175, a fluorescent lamp is described which includes a plurality of phosphors in addition to a mercury filling. Diese werden durch die UV- Strahlung (254 nm) oder auch durch die kurzwellige Strahlung bei 460 nm angeregt. These are produced by the UV radiation (254 nm) or by the short-wave radiation at 460 nm excited. Drei Leuchtstoffe sind so gewählt, daß sie sich zu weiß addieren (Farbmischung). Three phosphors are selected so that they add up to white (color mixing).

Darstellung der Erfindung Summary of the Invention

Es ist Aufgabe der vorliegenden Erfindung, einen Leuchtstoff gemäß dem Oberbe griff des Anspruchs 1 bereitzustellen, der beständig gegen hohe thermische Bela stung ist und sich gut für die Anregung im kurzwelligen sichtbaren Spektralbereich eignet. It is an object of the present invention, a phosphor according to the Oberbe handle of claim 1 which is resistant to high thermal loading stung and is well suited for excitation in the short-wave visible spectral range.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. This object is solved by the characterizing features of claim 1. Besonders vorteilhafte Ausgestaltungen finden sich in den abhängigen Ansprüchen. Particularly advantageous configurations are given in the dependent claims.

Erfindungsgemäß wird ein Leuchtstoff für Lichtquellen, deren Emission im kurzwelli gen optischen Spektralbereich liegt, verwendet, der eine Granatstruktur A 3 B 5 O 12 besitzt und der mit Ce dotiert ist, wobei die zweite Komponente B mindestens eines der Elemente Al und Ga repräsentiert, wobei die erste Komponente A Terbium ent hält. According to the invention there is provided a phosphor for light sources whose emission is in the kurzwelli gen optical spectral range, is used, having a garnet structure A 3 B 5 O 12 and doped with Ce, the second component B representing at least one of the elements Al and Ga, wherein the first component A terbium ent holds. Überraschenderweise hat sich herausgestellt, daß sich Terbium (Tb) unter be sonderen Umständen, nämlich bei blauer Anregung im Bereich 400 bis 500 nm, als wesentlicher Bestandteil des Wirtsgitters (erste Komponente des Granats) für einen gelb emittierenden Leuchtstoff eignet, dessen Dotierstoff Cer ist. Surprisingly, it has been found that terbium (Tb) under down specific conditions, namely under blue excitation in the range 400 to 500 nm, as an essential component of the host lattice (first component of the garnet) for a yellow-emitting phosphor is suitable whose dopant cerium. Bisher wurde es in diesem Zusammenhang lediglich als Aktivator neben Cer für die Emission im Grü nen in Betracht gezogen. So far, it has been considered in this context only as an activator in addition to cerium for emission in Grü nen.

Dabei kann Terbium als Hauptbestandteil der ersten Komponente A des Granats in Alleinstellung oder zusammen mit mindestens einer der Seltenerdmetalle Y, Gd, La u/o Lu verwendet werden. It can be used terbium as the main constituent of the first component A of the garnet alone or together with at least one of rare earth elements Y, Gd, La and / or Lu.

Als zweite Komponente wird mindestens eines der Elemente Al oder Ga verwendet. As a second component at least one of Al or Ga is used. Die zweite Komponente B kann zusätzlich In enthalten. The second component B may additionally contain In. Der Aktivator ist Cer. The activator is cerium.

In einer besonders bevorzugten Ausführungsform wird ein Granat der Struktur In a particularly preferred embodiment, a garnet of the structure
(Tb 1-xy SE x Ce y ) 3 (Al, Ga) 5 O 12 verwendet, wobei (Tb 1-xy SE x Ce y) 3 (Al, Ga) 5 O, used 12 wherein
SE = Y, Gd, La und/oder Lu; SE = Y, Gd, La and / or Lu;
0 < = x < = 0,5-y; 0 <= x <= 0.5-y;
0 < y < 0,1 gilt. 0 <y <0.1 applies.

Der Leuchtstoff absorbiert im Bereich 400 bis 500 nm und kann so durch die Strah lung einer blauen Lichtquelle, die insbesondere die Strahlungsquelle für eine Lampe oder LED ist, angeregt werden. The phosphor absorbs in the range 400 to 500 nm and can thus by the radia tion a blue light source, which is in particular the radiation source for a lamp or LED, are excited. Gute Ergebnisse wurden mit einer blauen LED er zielt, deren Emissionsmaximum bei 430 bis 450 nm lag. Good results were achieved with a blue LED, it aims whose emission maximum was at 430 to 450 nm. Das Maximum der Emissi on des Tb-Granat : Ce-Leuchtstoffs liegt bei etwa 550 nm. The maximum of the TERMS on the Tb-garnet: Ce phosphor is about 550 nm.

Dieser Leuchtstoff eignet sich besonders für die Verwendung in einer weißen LED, beruhend auf der Kombination einer blauen LED mit dem Tb-Granat-Leuchtstoff, der durch Absorption eines Teils der Emission der blauen LED angeregt wird und des sen Emission die übrig bleibende Strahlung der LED zu weißem Licht ergänzt. This phosphor is particularly suitable for use in a white LED, based on the combination of a blue LED with the Tb-garnet phosphor, which is excited by absorption of part of the blue LED emission and sen emission, the remaining radiation from the LED added to white light.

Als blaue LED eignet sich insbesondere eine Ga(In)N-LED, aber auch jeder andere Weg zur Erzeugung einer blauen LED mit einer Emission im Bereich 400 bis 500 nm. Insbesondere wird als hauptsächlicher Emissionsbereich 430 bis 450 nm emp fohlen, da dann die Effizienz am höchsten ist. As a blue LED is suitable in particular a Ga (In) N-LED, but any other way to produce a blue LED with an emission in the range 400 to 500 nm. In particular, from 430 to 450 nm as the main emission region foal emp, since then the efficiency is highest.

Durch die Wahl von Art und Menge an Seltenerdmetallen ist eine Feineinstellung der Lage der Absorptions- und der Emissionsbande möglich, ähnlich wie dies für andere Leuchtstoffe des Typs YAG : Ce aus der Literatur bekannt ist. By choosing the type and amount of rare earth metals, fine adjustment of the position of the absorption and emission bands is possible, similar to that for other phosphors of the type YAG: Ce is known from the literature. In Verbindung mit Leuchtdioden eignet sich vor allem ein Bereich für x, der zwischen 0,25 ≦ x ≦ 0,5-y liegt. In conjunction with light emitting diodes mainly a range of x which is between 0.25 ≦ x ≦ 0.5 y is suitable.

Der bevorzugte Bereich von y liegt bei 0,02 < y < 0,06. The preferred range of y is 0.02 <y <0.06.

Der erfindungsgemäße Leuchtstoff eignet sich auch zur Kombination mit anderen Leuchtstoffen. The phosphor according to the invention is also suitable for combination with other phosphors.
