YVO4 has good chemical stability,which can be doped easily by tervalence rare earths easily.YVO4:Eu nanoparticales were prepared using hydrothermal synthsis method and characterized by XRD and TEM.The results indicated that all of the samples were tetragonal phase with complete morphology and well-distributed sizes.The results of emission spectra indicated that the samples showed different emission peaks at different temperature.The samples prepared at 2000C showed characteristic peaks of Eu3+ions,and the strongest peak appeared at 619 nm.
