In this experiment, ammonium metavanadate (NH4VO3) and zinc nitrate Zn (NO3) 2 as raw materials, combustion Zn3V2O8 yellow phosphor prepared by using X-ray diffraction pattern (XRD), scanning electron microscopy (SEM) and emission spectrum Study on the crystal structure of the test Zn3V2O8 phosphor morphology analysis and optical properties, in order to obtain vanadate matrix fluorescent material having excellent thermal stability and chemical stability, can be widely used in lighting and displays. Introduction The studied of energy conservation and environmental protection lighting technology and green illuminant material become a hot focus in the energy shortage and environment pollution problem increasingly prominent conditions. The white LED have been obtain by the near ultraviolet stimulate single chip substrate technology, it have light color stability, high color rendering and low production cost advantage, become the future development trend of the LED light materials. The Zn3V2O8 phosphor is a kind of better luminous properties material. The effective sensitization between VO4 and rare earth, self-activated the luminescence properties exist in the electronic structure of Zn3V2O8 phosphor, it leader to the Zn3V2O8 phosphor present to short wave absorption and matrix material with doped rare earth ions. The theoretical analysis and experimental study results shows that Zn3V2O8 phosphor have a width emission spectrum . Recent research shows the color rendering property of red YVO4 phosphors was increased by rare earth Eu doped. Whereafter, (Y, Gd, Lu)VO4, ScVO4 and (K, Rb, Cs)VO3 phosphors have been compound by rare earth Eu doped. The M2V2O7 (M: Ba, Sr, Ca) phosphors have been compound and the luminescence process of the regular tetrahedron structure of VO4 have been studied by A.V. Ishchenko, Kuang Shaoping and T. Nakajima. The Zn3(VO4)2 phosphors have been compound using Hydrothermal synthesis method and citric acid gel combustion method by Shreyas S.Pitale. The Mg2V3O12:Dy, Sm phosphors have been compound and the luminescence process of Sm-doped and Dy-doped by A.R. Dhobale . In this paper we used Combustion Synthesis method the Zn3V2O8 phosphor, in order to improve the compound cast and luminescence property of Zn3V2O8 phosphor.

The effect in the crystal phase and luminescence property of Zn3V2O8 with calcinations temperature
