The gold nanoparticle acts as an antenna, absorbing light that can then be transferred to the bound rare-earth oxide (see Figure), enhancing the oxide luminescence by a factor of 40. This could provide a route to enhanced fluorescence labels for biological systems based on optimized absorber and emitter nanocomposite tags.Silica-GelsNanoparticlesFluorescenceNanocrystalsSizeEnhancementNucleationParticlesChelatetext::journal::journal article::research article
