Abstract

Die Erfindung schlägt eine dielektrische Barriere-Entladungslampe mit einer Leuchtstoffmischung und die Verwendung einer dielektrischen Barriere-Entladungslampe mit einer Farbtemperatur von mindestens 10 000 K für die Betrachtung von Röntgenbildern vor. Die Leuchtstoffmischung besteht aus den Leuchtstoffkomponenten R: Europium aktiviertes Yttriumgadoliniumborat ([Y, Gd]BO3:Eu), G: Terbium aktiviertes Lanthanphosphat (LaPO4:[Tb]) oder Cer und Terbium aktiviertes Lanthanphosphat (LaPO4:[Ce, Tb]) und B: Europium aktiviertes Bariummagnesiumaluminat (BaMgAl10O17:Eu). Für die Gewichtsanteile der Mischung gilt: 0,05 ≤ R ≤ 0,15 , 0,50 ≤ G ≤ 0,70 , 0,20 ≤ B ≤ 0,40 und R + G + B = 1.

The invention proposes a dielectric barrier discharge lamp with a phosphor mixture and the use of a dielectric barrier discharge lamp with a color temperature of at least 10,000 K for viewing X-ray images. The phosphor mixture consists of the phosphor components R: europium activated yttrium gadolinium borate ([Y, Gd] BO 3 : Eu), G: terbium activated lanthanum phosphate (LaPO 4 : [Tb]) or cerium and terbium activated lanthanum phosphate (LaPO 4 : [Ce, Tb ]) and B: europium activated barium magnesium aluminate (BaMgAl 10 O 17 : Eu). For the proportions by weight of the mixture: 0.05 ≤ R ≤ 0.15, 0.50 ≤ G ≤ 0.70, 0.20 ≤ B ≤ 0.40 and R + G + B = 1.
