[摘要]：Emission by rare earth emitters has been experimentally investigated based on their position relative to metallic nanoparticles by using Ag/Y2O3/Eu:Y2O3/Y2O3/Ag multilayer samples on-or off-plasmon resonance. Comparison with simple models revealed two different coupling regimes at short and long distances. The optimal coupling distance was determined. (C) 2012 American Institute of Physics.
