Surface plasmon enhanced nanostructure design using FDTD simulation for improving luminous efficacy of Polymer Light-emitting devices.

摘要

We demonstrated a systematic stuYYyydy on localized surface plasmon resonance of hexagonal Ag nano dot structure using Finite Descrete Time Domain(FDTD) tool. From the simulation result, First, Designed PLED structure's absorption spectrum is proved theoretically. Second, It was found out that changing Ag dot lattice cosnstant smaller causes blue shifted absorption peak which becomes closer to MEH-PPV emission wavelength.. It could increase in spontaneous rate owing to surface plasmon excitation emission coupling.
