Ce travail présente une nouvelle diode électroluminescente organique à émission de champ (FEOLED), dans laquelle un film mince de phosphore inorganique est remplacé par une couche électroluminescente organique EL dans la configuration d'un écran à émission de champ (FED). Les électrons d'émission de champ émis par la cathode de nanotubes de carbone (CNT) du FEOLED proposé intensifient la densité électronique dans les matériaux organiques multicouches de l'OLED ; il en résulte ainsi une efficacité lumineuse supérieure à celle d’une OLED conventionnelle. De plus, la luminance du FEOLED proposé peut être encore augmentée, passant de 10,820 XNUMX cd/m2 à 27,393 cd/m2 en augmentant la densité de courant de l'OLED via une source d'électrons externe. Une quantité équilibrée d'électrons et de trous dans l'OLED, obtenue par le FEOLED proposé, augmente le nombre d'excitons et attribue l'amélioration de l'efficacité lumineuse de l'OLED. Sous la même densité de courant de fonctionnement, la FEOLED proposée présente une efficacité lumineuse supérieure à celle d'une OLED conventionnelle.

Abstract: This work presents a novel field emission organic light emitting diode (FEOLED), in which an inorganic phosphor thin film is replaced by an organic EL light-emitting layer in the configuration of a field emission display (FED). The field emission electrons emitted from the carbon nanotubes (CNTs) cathode of the proposed FEOLED intensify the electron density in the multi-layer organic materials of the OLED; thus, resulting a higher luminous efficiency than that of a conventional OLED. Additionally, the luminance of the proposed FEOLED can be further increased from 10,820 cd/m2 to 27,393 cd/m2 by raising the current density of OLED through an external electron source. A balanced quantity of electrons and holes in the OLED, which is achieved by the proposed FEOLED increases the number of excitons and attributes the enhancement of luminous efficiency of the OLED. Under the same operating current density, the proposed FEOLED exhibits a higher luminous efficiency than that of a conventional OLED.
