Notes:
Single phase of Ba1-xEuxMgAl10O17(0.02≤x≤0.14) phosphors were first successfully prepared by coprecipitation method at 1300℃, which is 300℃ lower than the temperature of solid-state method. Different precipitants were used to evaluate the changes in the morphology and luminance properties. When using (NH4)2CO3 as precipitant, the phosphor particle without agglomeration has a more regular shape and uniform distribution. Their photoluminescence wasinvestigated under UV and VUV region, respectively. The emission spectrum excited by 254nm or 147nm showed a characteristic wide band with the peak at about 450nm. The synthesized phosphor showed much stronger emission intensity than that prepared by solid-state method, especially using (NH4)2CO3 as precipitant, it indicated that this novel process will be great potential in practical use
