Abstract
YVO4:Eu hollow microspheres have been successfully fabricated via a urea-based homogeneous precipitation method in the presence of colloidal melamine formaldehyde resin (MF) microspheres as templates, without heat treatment. X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), photoluminescence (PL) spectra, and the kinetic decay were employed to examine the resulting phase formation, morphology and luminescent properties. The XRD result reveals that the doped sample is of high crystallization which is assigned to the pure tetragonal phase of YVO4. Upon excitation by ultraviolet excitation, the YVO4:Eu sample shows strong red light emission.
