摘要：
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.
