In this investigation, a simple, rapid, and low-cost sputtering system was employed to deposit a Au-nanoparticles (Au-NPs) layer in polymer light-emitting diode (PLED) at roomtemperature. The green-emitting PLEDs considered herein are single-layer devices based on a poly[9,9-dioctylfluorene-co-benzothiadiazole] emissive layer. This novel fabrication effectively avoids interruption or degradation of the charge transport properties of the active layer and therefore satisfies the high performance requirements for PLEDs. Because of the surface-plasmon-enhanced emission, the electroluminescence intensity of the green-emitting PLED based on the Au-NPs/ITO anode increased nearly 2.7-fold, compared to that of the standard green-emitting PLED with a bare ITO substrate.
