45067 2018 eng poster 0 -- -- -- Synthesis and systematic characterization of core-muti-shell NaYF4:Er3+, Yb3+@SiO2@Au nanoparticles for the enhancement of fluorescence emission The aim of this work is to investigate the Synthesis of core-shell upconverting nanoparticles (UCNP). The UCNP are coated with a Gold Shell to plasmonically enhance the fluorescence emision. The distance between the UCNP core and the plasmonic structure is tuned by the aid of a silica at different Shell thicknesses.
