We have investigated the borderline between photoluminescence quenching and enhancement of InGaN/GaN quantum-wells due to Ag nanoparticles and their surface plasmon modes. By embedding Ag
nanoparticles inside nanohole structures on the p-type layer GaN, luminescence quenching is observed.Increasing the distance between the nanoparticles and quantum-wells has shown to enhance the
emission. We have found that the nano-structure geometry of the metal-semiconductor interface in the near-field of the quantum-wells plays a crucial role in determining whether the emitter performance is enhanced or degraded.
