Yttrium substituted barium thioaluminate phosphor materials

Luminous material of electroluminescent element film luminous material, wherein elects from the sulfo- aluminate, the sulfo- gallate and sulfo- indium anode salt; and at least one is preferably from the periodic table of IIA and IIB element group the positive ion. The luminescent is made of activated of the metal; and included IIIB element group of the sulfo- part, aluminium on the or the indium gallate, the sulfo- indium anode and connecting sulfo- according aluminate substituted on contacts. Luminous material is connected with the logic improved. At the invention describes further comprises a thin film luminous material electroluminescent device on a substrate.
