Abstract

We synthesized Zn3V2O8, CsVO3 and Cs3VO4 by sol-gel process and studied their crystalline and luminescent properties. By optimizing the sintering conditions, pure phases of aim samples including Cs3VO4 were obtained. The annealing temperatures of 450℃ for CsVO3, 600℃ for Cs3VO4, respectively, are lower than that of 750℃ for Zn3V2O8 at the same duration of 12h. The Cs3VO4 showed quantum yield of 90% with the half-width of 120nm. It became clear that the Cs-V-O system, especially Cs3VO4, is promising for white LED applications.
