Abstract

During the past decade, dramatic efforts have been dedicated to exploring rare-earth doped nanoparticles, whose optical properties and low cytotoxicity are promising for biological application¹. Yttrium orthovanadate (YVO₄), which crystallizes in a zircon-type structure, has received considerable interest due to its suitable lattice structure for doping with rare earth elements. YVO₄:Eu³⁺ is an important red emitting phosphor while it was used widely in color television, high-pressure mercury lamp. In particular, YVO₄:Eu³⁺ nanocrystal is promising material for biological applications.
