| 摘 要： | 以氧化铒、氧化钇、硝酸铝及柠檬酸作为起始原料,采用溶胶-凝胶燃烧法制备50%Er3 (摩尔分数)掺杂的Y3Al5O12(YAG)纳米粉体.通过热重-差热分析仪,X射线衍射仪、红外光谱仪和透射电镜研究Er3 :YAG粉体的相变过程、结构和形貌.结果表明:烧结温度小于900℃时,前驱体粉末直接转变为纯YAG晶相,不形成任何中间相.随着烧结温度的增加,晶粒尺寸增大.在900℃烧结的粉体尺寸约为70～150nm,有利于制备性能优异的Er3 :YAG陶瓷. |

| Abstract: | The sol-gel combustion method was used to synthesize 50%Er3+(in mole) doped Y3Al5O12(YAG) nanopowder, using er-bium oxide, yttria, aluminum nitrate and citric acid as starting materials. The phase transformation, structure and morphology of Er3+:YAG precursor and the calcined powder were studied by means of thermogravimetric-differential thermal analysis, X-ray pow-der diffraction, infrared, and transmission election microscope methods. It was found that the precursor is converted directly into pure YAG at a relatively lower temperature (below 900℃) without any other intermediate phase. The crystalline size grew with the in-crease of the heat treatment temperature. The size of powder calcined at 900℃ was about 70-150nm, which is favorable for good sinterability of Er3+:YAG ceramics. |
