Luminescence materials doped with rare earths have been studied in the past few decades because of their wide applications in lighting and laser displays [1]. The rare earth ion activated luminescence material such as Y2O2, YVO4, and YBO3 are used as host because of their single crystal structure and high chemical stability. LaVO4 was prepared by the combustion method. The structure and luminescence properties of LaVO4 have been studied. Photoluminescence showed a strong red emission peak at 5Do-7F2 transition at 616 nm. This is due to energy transfer to Eu3+ ions followed by absorption of UV light in the VO43- group. X-ray diffraction (XRD) spectra indicated that YVO4:Eu3+ thin films phosphor material is successfully prepared by combustion.
