Abstract

L'invention porte sur un dispositif électroluminescent organique (1) comprenant une anode (3), une cathode (4) et une couche de film mince organique (5) agencée entre l'anode (3) et la cathode (4). Le dispositif électroluminescent organique (1) est caractérisé par le fait que la couche de film mince organique (5) a une couche émettant de la lumière fluorescente (51), qui est composée d'une ou plusieurs couches et contient un ou plusieurs hôtes fluorescents et deux dopants fluorescents ou plus émettant de la lumière fluorescente, et une couche émettant de la lumière phosphorescente (52) contenant un hôte phosphorescent et un dopant phosphorescent émettant de la lumière phosphorescente rouge. Le dispositif électroluminescent organique (1) est en outre caractérisé par le fait que la bande interdite de triplet excité la plus basse EgFH d'au moins l'un des hôtes fluorescents et la bande interdite de triplet excité la plus basse EgPD du dopant phosphorescent satisfont la relation suivante : EgPD < EgFH.
