| Abstract: | The green phosphor(Ce,Tb)MgAl11O19 was prepared by using microwave synthesis,the result of orthogonal experimentation was analyzed.The optimal process conditions were the holding time 90 min,the calcination temperature 1 450 ℃,the heating rate 15 ℃/min.The samples were characterized by the methods of fluorescence spectrophotometer,particle size analyzer and X-ray diffractometer.The result showed that the maximum peak in the emission spectrum was located at 545 nm,the relative brightness was 102.2%,the color coordinates x = 0.323 4;y = 0.597 4,and centre granular diameter of powder body D50 = 6.59 μm,distribution of grain size was uniform. |
