Organic light-emitting diodes (OLEDs) have studied over last few decades due to their many advantages for potential applications in displays, and lightings. One remarkable way to enhance the efficiency of OLEDs is to introduce localized surface plasmon resonance (LSPR) into OLEDs. Herein, we reports new and simple method to couple localized surface plasmons from Ag nanoparticles (NPs) with emissive materials. First of all, PVP-capped Ag NPs were successfully synthesized and analyzed by scanning electron microscope (SEM) and UV-Vis spectrophotometer. To attach the Ag NPs on the ITO substrate, 11-mercaptoundecanoic acid (11-MUA) was introduced on the ITO surface. Then Ag NPs capped with PVP was deposited by drop-casting on the ITO substrate. Ag NPs were attached on the ITO through ligand-exchange process on the surface. Properties of Ag NPs film was measured by various techniques. Finally, localized surface plasmon coupled OLED based on functionalized Ag NPs film was fabricated. |
