Enhancement of exciton emission in a semiconductor thin film decorated with plasmonic nanoparticles

Plasmonic nanoparticles can be used to engineer radiation decay of a dipole in close proximity to the surface of the particle. We present a theoretical analysis of the quantum yield of an electric dipole near a silver or gold nanoparticle of several different sizes. Specifically, we detail the calculation and simulation of the normalized quantum yield of an electric dipole coupled with a plasmonic nanoparticle. We find that the local electric field near the electric dipole is enhanced and has its characteristics altered.
