In addition, the Au/GdVO 4:Eu NRs exhibit bright Eu 3+ fluorescence with quantum yield as high as ~17% bright Sm 3+ and Dy 3+ fluorescence can also be obtained by changing the lanthanide doping in the oxide formation. Owing to the carefully designed strategy, the AuNR cores maintain the morphology during the synthesis process thus, the final Au/GdVO 4:Eu core/shell NRs exhibit strong absorption bands and high photothermal efficiency. Furthermore, the composition of the shell has been altered from oxide to vanadate (GdVO 4:Eu) using an anion exchange method. After modifying the AuNR surface with oleate through a surfactant exchange, well-packaged rare-earth oxide (e.g., Gd 2O 3:Eu) shells are grown on AuNRs as a result of the multiple roles of oleate. Herein, we report a synthetic route to grow rare-earth-vanadate shells on gold nanorod (AuNR) cores. The nanoscale core/shell heterostructure is a particularly efficient motif to combine the promising properties of plasmonic materials and rare-earth compounds however, there remain significant challenges in the synthetic control due to the large interfacial energy between these two intrinsically unmatched materials.
