Abstract

La présente invention concerne un écran ou un tube luminescent muni d'une substance luminescente Dans sa forme de réalisation préférée, la substance luminescente de l'invention est un composé ternaire ABC dont les phases ont pour formule générale M3 LN (PO 4 )2 dans laquelle M est au moins l'un des éléments choisi parmi le groupe constitué par Na, K, Rb, Cs. Ln est au moins l'un des élements choisi parmi le groupe constitué par Ce, Tb, Gd, Dy et éventuellement La, Y, Sc. Les écrans ou les tubes luminescents munis de telles substances sont applicables aux lampes à décharge dans la vapeur de mercure, aux tubes à rayons cathodiques et aux dispositifs de conversion rayons X, visibles ou rayons X -U.V. - U.V. - visibles ou U.V. - U.V.The present invention relates to a luminescent screen or tube provided with a luminescent substance In its preferred embodiment, the luminescent substance of the invention is a ternary compound ABC whose phases have the general formula M3 LN (PO 4) 2 in which M is at least one of the elements selected from the group consisting of Na, K, Rb, Cs. Ln is at least one of the elements chosen from the group consisting of Ce, Tb, Gd, Dy and optionally La, Y, Sc. Luminescent screens or tubes provided with such substances are applicable to gas discharge lamps. mercury, cathode ray tubes and X-ray, visible or X-UV converter devices - U.V. - visible or U.V. - U.V.
