Research Abstract

Luminescence enhancement of ZnO nanoparticles on metal surfaces has been studied. Emission intensity of exciton transition is about tens of times for Ag than that for quartz surface, and strongly depends on the kind and surface roughness of metal. The intensity increases remarkably when the particle size is almost the same as the roughness. The enhancement is partially attributed to suppressing of the nonradiative recombination. Emission intensity in ZnO nanoparticles on the Ag surface with inverse-Pyramid structure increases as compared with no structure. In an application of these results, random laser was observed from ZnO nanoparticles dispersed on the rough surface of metal successfully.
