Abstract

L'invention porte sur un dispositif électroluminescent organique comprenant une anode, une cathode et une couche à film mince organique, agencée entre l'anode et la cathode. La couche à film mince organique présente une couche émettant de la lumière fluorescente contenant un hôte fluorescent et un dopant fluorescent, et une première couche émettant de la lumière phosphorescente contenant un premier hôte phosphorescent et un premier dopant phosphorescent. Lorsque la bande interdite de triplet de l'hôte fluorescent est exprimée par EgfH et la bande interdite de triplet du premier hôte phosphorescent est exprimée par EgpH1, elles satisfont la relation suivante : EgfH > EgpH1.
