Title (EN) PRINTED ELECTROLUMINESCENT DEVICE
(FR) DISPOSITIF ÉLECTROLUMINESCENT IMPRIMÉ
Abstract:
(EN) A printed electroluminescent device is taught. The printed electroluminescent device comprises a bottom conducting layer on top of a substrate. An electroluminescent phosphor layer provided on top of the bottom conducting layer. A polymeric conducting layer provided on top of the electroluminescent phosphor layer. The electroluminescent phosphor layer comprises at least one phosphor particle and at least one anchoring molecule. The anchoring molecule comprises at least one first functional group and at least one second functional group. The at least one first functional group is covalently bonded to a surface of the at least one phosphor particle. The polymeric conducting layer comprises at least one polymer chain. The at least one polymer chain comprises at least one third functional group. Some of the at least one third functional group are covalently bonded to some of the at least one second functional group.
(FR) L'invention concerne un dispositif électroluminescent imprimé. Le dispositif électroluminescent imprimé comprend une couche conductrice inférieure sur le dessus d'un substrat. Une couche de phosphore électroluminescent est disposée au-dessus de la couche conductrice inférieure. Une couche conductrice polymère est disposée au-dessus de la couche de phosphore électroluminescent. La couche de phosphore électroluminescent comprend au moins une particule de phosphore et au moins une molécule d'ancrage. La molécule d'ancrage comprend au moins un premier groupe fonctionnel et au moins un deuxième groupe fonctionnel. Le ou les premiers groupes fonctionnels sont liés de manière covalente à une surface de la ou des particules de phosphore. La couche conductrice polymère comprend au moins une chaîne polymère. La ou les chaînes polymères comprennent au moins un troisième groupe fonctionnel. Une partie du ou des troisièmes groupes fonctionnels est liée de manière covalente à une partie du ou des deuxièmes groupes fonctionnels.
