We report surface plasmon enhanced up-conversion in NaYF4:Yb3+,Er3+ phosphor nanoparticles. A silver nanograting structure was used to produce a surface plasmon resonance at the energy of the Förster transfer process. The enhanced up-converted Er3+ luminescence intensity, and shortened decay time of the Yb3+ luminescence, confirms surface plasmon enhancement of the Förster transfer process between Yb3+ and Er3+.
