Title (EN) ORGANIC ELECTROLUMINESCENCE ELEMENT
(FR) ELEMENT ELECTROLUMINESCENT ORGANIQUE
Abstract:
(EN) An organic electroluminescence element which has a luminous layer made of at least an organic material and formed between a hole injection electrode and an electron injection electrode. The host material of the luminous layer is doped with a dopant having three or more condensed rings. The difference between the highest occupied level in the host material and that of the dopant is -0.3 eV to +0.3 eV.
(FR) L'invention a pour objet un élément électroluminescent organique possédant une couche lumineuse fabriquée au moins à partir d'un matériau organique et formée entre une électrode d'injection de trous et une électrode d'injection d'électrons. Le matériau hôte de la couche lumineuse est dopé avec un dopant possédant au moins trois cycle condensés. La différence entre le niveau le plus élevé occupé dans le matériau hôte et celui du dopant est comprise entre -0,3 eV et +0,3 eV.
