General description
Green up-conversion phosphor
Application
Sodium yttrium fluoride, ytterbium and erbium doped (NaYF4: Yb3+/Er3+) is a rare earth doped NaYF4, which can be used for a variety of applications, which include color display, solar cells, photocatalysis, and bioimaging.[1] It can be used in the synthesis of NaYF4: Yb3+/Er3+ based upconversion nanoparticles (UCNPs).[2]

We report a five-fold overall enhancement of upconversion emission in NaYF(4) : Yb/Er nanocrystals when coupled with gold island films. Spectroscopic studies show that the enhancement factors are highly dependent on the exact spectral positions and excitation power density, with a largest
