(FR) LUMINOPHORES ÉMETTANT DES RAYONNEMENTS UV
Abstract: front page image
(EN)The invention provides a wavelength converting material comprising a compound of the formula (Y1-w-x-y-zScwLaxGdyLuz)2-a(S04)3:Mea, wherein Me represents trivalent cation or a mixture of trivalent cations capable of emitting UV-C radiation, and wherein each of w, x, y and z is in the range of from 0.0 to 1.0 and w+x+y+z ≤ 1.0, and wherein 0.0005 ≤ a ≤ 0.2. The wavelength converting material may be applied in an illumination device for UV illumination, in particular for sterilization or disinfection by germicidal UV illumination.
(FR)L'invention concerne une matière de conversion de longueur d'onde comprenant un composé de formule (Y1-w-x-y-zScwLaxGdyLuz)2-a(S04)3:Mea, où Me représente un cation trivalent ou un mélange de cations trivalents capable d'émettre un rayonnement UV-C, et où chacun de w, x, y et z se situe dans la plage allant de 0,0 à 1,0 et w+x+y+z ≤ 1,0 et où 0,0005 ≤ a ≤ 0,2. La matière convertissant une longueur d'onde peut être utilisée dans un dispositif d'éclairage pour un éclairage UV, en particulier pour la stérilisation ou la désinfection par un éclairage UV germicide.
