A series of Ba2SiO4∶Eu2+ green phosphors have been synthesized by high temperature solid state method.The effects of different fluxes on the crystal structure,surface morphology and spectral characteristics of Ba2SiO4∶Eu2+ phosphors were systematically investigated by X-ray powder diffraction(XRD),scanning electron microscopy(SEM) and fluorescence spectrophotometer.The function mechanism of different fluxes on the preparation of Ba2SiO4∶Eu2+ phosphors have also been discussed.XRD results show that the Ba2SiO4∶Eu2+ phosphor without flux has the impurity phase of BaSi2 and SiO2 during firing,while fritted with NH4F,Na2CO3 or H3BO3 flux,the impurity phase of BaSi2 can be suppressed.BaF2 flux can get the pure orthorhombic.By comparing the influence of different fluxes on the emission of Eu2+,it was found that the emission intensity of the Ba2SiO4∶Eu2+ phosphor with 2% mass fraction of BaF2,NH4F or Na2CO3 flux improved by 138%,81%,34% than that of the powder without the flux material,while the luminescent intensity reduced 14% when using 2% mass fraction of H3BO3 as flux.The phosphor powders were spherical-like shapes using BaF2 as the flux,while the phosphor powder prepared with NH4F,Na2CO3 or H3BO3 as flux had the irregular laminated structure,spindle shape and irregular polygon,respectively.
