Title (EN) LIGHT-EMITTING ELEMENT, LIGHTING DEVICE, AND ELECTRONIC APPLIANCE
(FR) ÉLÉMENT ÉLECTROLUMINESCENT, DISPOSITIF D'ÉCLAIRAGE ET APPAREIL ÉLECTRONIQUE
Abstract:
(EN) A tandem light-emitting element employing an inverted-structure is provided. The light-emitting element includes a cathode, a first EL layer over the cathode, a second EL layer over the first EL layer, an anode over the second EL layer, and an intermediate layer. The intermediate layer is between the first EL layer and the second EL layer. The intermediate layer includes a first layer, a second layer over the first layer, and a third layer over the second layer. The first layer includes a hole-transport material and an electron acceptor. The third layer includes an alkali metal or an alkaline earth metal. The second layer includes an electron-transport material.
(FR) Cette invention concerne un élément électroluminescent en tandem mettant en œuvre une structure inversée. Ledit élément électroluminescent comprend une cathode, une première couche électroluminescente au-dessus de la cathode, une seconde couche électroluminescente au-dessus de la première couche électroluminescente, une anode au-dessus de la seconde couche électroluminescente, et une couche intermédiaire. Ladite couche intermédiaire est disposée entre la première couche électroluminescente et la seconde couche électroluminescente. Ladite couche intermédiaire comprend une première couche, une deuxième couche au-dessus de la première couche, et une troisième couche au-dessus la deuxième couche. Ladite première couche comprend un matériau de transport de trous et un accepteur d'électrons. Ladite troisième couche comprend un métal alcalin ou un métal alcalino-terreux. Ladite deuxième couche comprend une un matériau de transport d'électrons.
