Surface plasmons are charge density oscillations confined to metallic nanoparticles and nanostructures. These oscillations can occur at the interface between a metal and a dielectric medium. The collective response of electrons in surface of conductor to optical fields affects the spectroscopy of nearby molecules. The frequency and intensity of the surface plasmons are characteristic of the type of material, size, size distribution, and environments which surround them. Due to the quenching of emission by surface plasmons in the light emitting device, only few attempts have so far been made for the application to organic light emitting devices. In our presentation, we demonstrate enhanced PL intensity of organic fluorophores and OLED performance by using Ag thin film as a metal functionalized layer on the ITO which exhibit surface plasmons in the visible spectral region. |
