Periodic silver nanorods array have been used to improve the hole injection and the electroluminescence of organic LEDs (OLED). The nanorods have been fabricated on the indium tin oxide anode by electron beam lithography technique with a precise control of the nanoparticles parameters. The μ-OLEDs fabricated on top of the nanorods show higher-current density and lower turn-on voltages in comparison with the reference device. Moreover, the results emphasise the existence of the localised surface plasmon resonance enhancement effect as well as an important improvement of the hole injection from the anode.
