Paper Abstract

Highly dispersed and uniform α-NaYF4 micron flowers with about 500nm size was synthesized by a simple wet-chemical at a low temperature, then NaYF4:Eu3+@Au hybrid structures with various amount Au nanoparticles (Au NPs) are prepared and single NaYF4:Eu3+@Au hybrid particle is taken to investigate the influence of noble metal nanoparticle on the luminescence emission and present corresponding mechanism. It is found that luminescence emissions of NaYF4:Eu3+ was quenched by introducing Au nanoparticles, and with increase of Au nanoparticles, the fluorescence quenching was more and more serous while emission intensity ratio of electric dipole to magnetic dipole transition of Eu3+ gradually become larger.
