The present invention is directed to improved transparent electrically conductive buffer layers for light-emitting diodes. The use of an aqueous dispersion containing an electrically conducting polymer and a non-ionic surfactant or an ionic fluorosurfactant to form the buffer layer has been shown to provide a buffer layer that results in improved light-emitting diode performance.
La présente invention a trait à des couches tampon transparentes améliorées conductrices d'électricité pour des diodes électroluminescentes. Il a été démontré que l'utilisation d'une dispersion aqueuse contenant un polymère conducteur d'électricité et d'un tensioactif non ionique ou d'un tensioactif fluoré ionique pour constituer une couche tampon permet d'obtenir une couche tampon entraînant une performance améliorée des diodes électroluminescentes.
