Abstract In this paper,LiCl,NaCl,KCl or SrCl2 were selected as fluxes and the effect of the chlorides fluxes on crystallite,morphology and luminescence properties of the YAG∶Ce phosphor powders were investigated.It was found that the YAG∶Ce phosphors obtained from initiative materials containing chlorides fluxes exhibited typical garnet structure and no impurity phase.The YAG∶Ce particles are regular spherical or elliptical morphology,with small size and narrow granular distribution.The emission intensities of the YAG∶Ce phosphors increased with adding appropriate amounts of chlorides fluxes to initiative materials.The optimum amounts of chloride fluxes were 10% for LiCl,7% for NaCl,7% for KCl or 4% for SrCl2,respectively.
