The invention is a thin film phosphor structure that can be processed on a substrate comprising glass or glass ceramic coated with thin film electrode strips at lower temperatures. The improved phosphor structure for use in a thick film dielectric electroluminescent display comprises a phosphor laminate of a blue light emitting phosphor thin film layer and a thin fluoride containing layer provided directly adjacent the phosphor thin film layer, wherein the fluoride containing layer is provided on the top and/or bottom of the phosphor thin film layer.
L'invention concerne une structure phosphorescente en couche mince, qui peut être traitée sur un support comportant du verre ou de la céramique vitrifiée couverte de barrettes d'électrodes en couche mince à faibles températures. Cette structure phosphorescente perfectionnée, destinée à un affichage électroluminescent diélectrique en couche épaisse, comprend un stratifié phosphorescent composé d'une couche mince phosphorescente émettant de la lumière bleue et d'une couche mince contenant du fluorure, ces deux couches étant directement adjacentes et la couche contenant du fluorure se trouvant en haut et/ou en bas de la couche mince phosphorescente.
