Les effets de la photoirradiation sur les dispositifs électroluminescents polymères (PLED) dotés d'une cathode en Al semi-transparente ont été étudiés. Un polymère électroluminescent, un poly (p-phénylène vinylène) dérivé MDOPPV a été utilisé dans cette étude. Lors de la photoirradiation, l’intensité de l’émission à tension constante a rapidement diminué. Cependant, l’efficacité quantique de l’électroluminescence est restée constante, indiquant la séparation spatiale entre la zone de recombinaison et les défauts photooxydés. D’un autre côté, l’efficacité quantique de la photoluminescence a rapidement chuté lors d’une photoirradiation similaire. Ceux-ci peuvent être compris en prenant la différence de distribution spatiale et d’origine des excitons entre les processus d’électroluminescence et de photoluminescence. Il a également été constaté que le taux de photooxydation du film polymère dont l'épaisseur est d'env. 100 nm ne dépend pas de l'épaisseur, ce qui suggère que la photooxydation du polymère se déroule uniformément dans tout le dispositif.

Abstract: Photoirradiation effects on the polymer light-emitting devices (PLEDs) with a semitransparent-Al cathode have been studied. A light-emitting polymers, a poly (p-phenylene vinylene) derivative MDOPPV has been used in this study. Upon photoirradiation, the emission intensity at a constant voltage was rapidly decreased. However, the quantum efficiency of electroluminescence remained constant, indicating the spatial separation between recombination zone and photooxidized defects. On the other hand, the quantum efficiency of photoluminescence rapidly dropped upon similar photoirradation. These can be understood by taking the difference in the spatial distribution and the origin of excitons between electro- and photo-luminescence processes. It was also found that the photooxidation rate of the polymer film whose thickness is ca. 100 nm does not have thickness dependence, suggesting that the photooxidation of the polymer proceeds uniformly throughout the device.
