Title (EN) ORGANIC ELETTROLUMINESCENT DEVICE WITH LOW OXYGEN CONTENT
(FR) DISPOSITIF ELECTROLUMINESCENT ORGANIQUE A FAIBLE TENEUR EN OXYGENE
Abstract: front page image
(EN) An organic electroluminescent device comprising a cathode and an ode and, disposed therebetween, an organic layer has oxygen atoms accumulated near the int rface of the organic layer and the cathode in a maximum concentration of less than about 6 t%, the maximum concentration being expressed in terms of the peak maximum of a sputte profile of the Ois concentration near the interface of the organic layer and the cathode meas red by means of X-ray photo-electron spectroscopy. Having such an unprecedented low m imum oxygen concentration, the EL device has an extended operational lifetime.
(FR) Dispositif électroluminescent organique comportant une cathode et une anode et, entre les deux, une couche organique présentant des atomes d'oxygène accumulés à proximité de l'interface entre la couche organique et la cathode en une concentration maximum de moins d'environ 6 % at., exprimée en termes du maximum de crête d'un profil de pulvérisation de la concentration en Ols à proximité de l'interface entre la couche organique et la cathode, mesurée par spectroscopie photoélectronique par rayons X. Le dispositif électroluminescent, bénéficiant de manière unique d'une telle concentration maximum basse en oxygène, présente une durée de vie utile prolongée.
