    Abstract

    We report the influence of organic electroluminescence (OEL) device on the color tunability and emission efficiency enhancement by surface plasmon grating coupled emission (SPGCE). The effect of coupling active surface plasmon polaritons (SPPs) on the metal nanostructure grating with organic material interface was studied. The dispersion relation was obtained from angle-resolved emission measurements. The combination of organic/metal interface SPPs mode allows specific directional emission rather than isotropic emission. Control of light emission angle in the SPGCE is dependent upon the index of refraction at the organic/metal/dielectric interface. Recent experimental results and potential applications of an active plasmonics biosensor with enhanced resonant energy emission due to interactions on the organic/metal nano-grating were presented and discussed.
