  • Multilayer polymer light-emitting diodes for solid state lighting applications
    Patent number: 8076842
    Abstract: 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.
