Patent number: 8076842Abstract: Multilayer polymer light-emitting diodes (PLEDs) are demonstrated using semiconducting polymers blended with organometallic emitters as the emissive layer and one or both of an electron transport layer and a hole transparent layer on the appropriate electron injection and hole injection sides of the emissive layer. The transport layers reduce energy potential gaps between the hole injection electrode and the emissive polymer and between the electron injection electrode and the emissive polymer. A solvent-processing based procedure for preparing these devices is also disclosed It uses nonpolar solvent-based solutions of emissive polymers to form the emissive layer and polar solvent-based solutions to form the transport layers to minimize etching and other undesirable interactions as the multiple layers are being laid down.Type: GrantFiled: March 1, 2006Date of Patent: December 13, 2011Assignee: The Regents of the University of CaliforniaInventors: Xiong Gong, Alan J.
