Abstract
(EN)
Provided are: a composition that is useful for producing a luminescent element in which initial degradation is suppressed; and a luminescent element formed using the composition. This composition for a luminescent element contains a host material and a guest material. The host material contains an aromatic compound having a fused ring skeleton in which three or more benzene rings only are condensed. The guest material contains an aromatic amine compound. The total amount of copper atoms contained in the host material and copper atoms contained in the guest material is 30 ppb by mass or less relative to the total amount of the host material and the guest material.

L'invention concerne: une composition qui est utile pour produire un élément luminescent dans lequel une dégradation initiale est supprimée; et un élément luminescent formé à l'aide de la composition. Cette composition pour élément luminescent contient un matériau hôte et un matériau invité. Le matériau hôte contient un composé aromatique ayant un squelette de cycle fusionné dans lequel trois cycles benzène ou plus sont condensés uniquement Le matériau invité contient un composé amine aromatique. La quantité totale d'atomes de cuivre contenus dans le matériau hôte et les atomes de cuivre contenus dans le matériau invité est de 30 ppb en masse ou moins par rapport à la quantité totale du matériau hôte et du matériau invité.
(JA)
