Highly luminescent rare earth based materials is a fast growing area of materials research. Recently, much attention has been paid to develop upconversion materials due to this kind of materials have many promising characteristics, such as non-autobleaching, low auto-fluorescence, and high penetration depth in biological tissues.… It is ideal to use YVO4: Yb3+Er3+Eu3+ phosphors for bioimaging application being investigated. In this work, YVO4 (yttrium orthovanadate) nanoparticles were prepared for using melamine formaldehyde (MF) as a template. In this case, europium (Eu3+) and erbium (Er3+) were used as activators and ytterbium (Yb3+) as sensitizer, respectively. The results were characterized by X-ray diffraction (XRD), Fourier-transform IR spectroscopy (FTIR), scanning electron microscopy (SEM), transmission electron microscopy (TEM). In the present study, the material shows good emission intensity and upconversion properties when this material excitatied by UV and IR. YVO4: Yb3+Er3+Eu3+ material is design to apply for bio-imaging, photodynamic therapy, laser, and photovoltaics.
