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. It can be used in the synthesis of NaYF4: Yb3+/Er3+ based upconversion nanoparticles (UCNPs).
