[Preparation and luminescence properties of EuVO4].

The material of EuVO4 was prepared by solid state reaction, and the structure, crystal form and luminescence properties of the material were characterized by X ray diffraction spectrum, infrared spectrum analysis, excitation spectrum and emission spectrum, respectively. XRD was measured at different annealing temperature and the results indicate that V2O5 and Eu2O3 began to react around 600 degrees C, and the reaction almost finished at 700 degrees C with the component of product being EuVO4. The product is in tetragonal crystallographic structure, consistent with crystal EuVO4.
