| 摘要: | 采用新型的超声喷雾共沉淀法(UACM)技术, 以Lu2O3、Ce(NO3)3、Al(NO3)39H2O为原料, 制备了不同浓度Ce3+离子掺杂的Lu3Al5O12(LuAG)纳米粉体, 并研究了粉体在不同温度下的烧结性能, 对所获得的纳米粉体进行了X射线粉末衍射(XRD)、扫描电镜(SEM)和发射光谱等测试与分析. 结果显示: 应用UACM法制备的LuAG:Ce粉体颗粒具有分散性好、颗粒度均匀, 粒径分布范围窄(20~40nm). 在氮气氛下, 经1200℃处理后, LuAG:Ce具有最强的508nm荧光发射带, Ce3+离子在粉体内的最佳掺杂摩尔分数为0.7. |
| Abstract: | Ce3+ doped nano-Lutetium aluminum garnet powders are prepared by ultrasonic atomization and co-precipitation with Lu2O3, Ce(NO3)3 and Al(NO3)3(9H2O as raw materials, and the obtained powders are sintered at various temperature. XRD, SEM and florescence spectrophotometer are employed to characterize the phase composition, particle size and luminescence property of the nano-powder. The results show that the powder particles synthesized via this method are well dispersed, homogeneous and narrowly distributed in size (20-40nm). It is found from the photoluminescence spectra that Lu3Al5O12:Ce powder calcified at 1100℃ for 2h in N2 atmosphere has the strongest intensity at 508nm, and the best doping concentration of Ce3+ ion for reaching the maximum emission intensity of powder is about 0.7. |
