摘要：

The green-emitting(Ce,Tb)MgAl11O19(CTMA) phosphor was prepared by the conventional high temperature solid-state reaction method.The effect of fluxes on the crystal structure,particle morphology,size distribution and photoluminescence properties of CTMA phosphor was investigated by means of the X-ray powder diffraction,scanning electron microscopy and photoluminescence spectrum.The results showed that the addition of appropriate amount of MgF2-H3BO3 flux improved the phase purity of CTMA phosphor,and influenced the growth of different crystal plane;furthermore,the particle morphology of CTMA phosphor became regular and size distribution narrowed.In addition,the CTMA phosphor prepared with MgF2-H3BO3 flux displayed higher photoluminescence intensity than that of the phosphor prepared with MgF2,H3BO3 or without flux.As a result,the optimum content of fluxes was 0.10 mol/mol MgF2 and 0.04 mol/mol H3BO3,and the maximum photoluminescence intensity of the CTMA phosphor prepared with MgF2-H3BO3 flux was 167% of that of the phosphor prepared without flux.
