Molten Salt Synthesis and Photoluminescence of YVO4:Eu Microcrystalline Phosphors

Abstract:

Article Preview

Tetragonal phase of YVO4:Eu3+ powders have been successfully synthesized via a molten salt synthesis process. During the process, rare earth nitrates and ammonium vanadate were used as precursors, the mixture of KCl and NaCl as a molten salt. As shown in XRD and SEM, the resultant product was a pure phase of YVO4 without any other impurities. Under the excitation of 326 nm, all the materials show the characteristic emission of Eu3+ which is the strong red emission originating from the 5D0 level, with 5D0→7F2 at 619 nm as the most prominent group.
