Molten salt synthesis and color manipulation of YVO4:Bi3+,Eu3+ phosphors

Abstract Well-crystalline YVO4:Bi3+,Eu3+ phosphors were successfully synthesized by a simple and one-step molten salt synthesis (MSS) method. Unlike other traditional studies on YVO4:Bi3+,Eu3+ phosphors, Bi3+ ions in this sample not only play as a sensitized ion, but also play a role of luminescence center. And this YVO4:Bi3+,Eu3+ can achieve a wide-range color manipulation of its photoluminescence by regulating the proportional concentration between the Bi3+ and Eu3+ ions, which is expected that the present results show great potential to be used in current industrial applications.
