摘要：

Light enhancement of polymer light-emitting diodes (PLEDs) was observed by coupling through plasmonic nanostructures. Thermal evaporation was used to fabricate Ag nanoparticles sandwiched between a gallium-doped zinc-oxide (GZO) film and a glass substrate to form novel window materials for use in PLEDs. Due to both the mean work function promotion on GZO surface and the surface-plasmon-enhanced emission, the electroluminescence intensities of the proposed PLEDs were increased by nearly 3-fold and 5-fold for the blue and green emission bands, respectively, compared with that of the standard PLEDs.
