【摘要】 钇铝石榴石(简称为YAG)属于立方晶系,是一种重要的发光基质材料。以其优良的物理、化学、热学、光学性质以及机械性能,使其成为发光功能材料领域的研究热点之一。目前研究者已用高温固相法、沉淀法、燃烧法、水热与溶剂热法、溶胶-凝胶法、微波法、微乳液法、喷雾热解法以及静电纺丝法等方法成功地制备出纳米颗粒、纳米球、纳米纤维、纳米带以及同轴纳米纤维等稀土掺杂钇铝石榴石纳米材料。本文中总结了上述几种制备方法的研究进展,讨论了其优缺点,并结合在稀土掺杂钇铝石榴石纳米材料制备方面的工作,对稀土钇铝石榴石制备方法的发展方向做了展望。更多还原

【Abstract】 Yttrium Aluminum Garnet(Y₃Al₅O₁₂, denoted as YAG for short) has a cubic structure with a garnet structure and is extensively used as luminescent matrixes. The rare-earth-doped YAG has become one of the popular research subjects in the realm of optical functional materials in recent years due to its superior physical, chemical, thermal, optical and mechanical properties. Recently many methods have been successfully applied for preparation of rareearth-doped YAG nanometerials with different shapes, such as, nanoparticles, nanospheres, nanofibers, nanobelts and coaxial nanofibers, etc., including high temperature solid state method, precipitation method, combustion method, hydrothermal and solvothermal method, sol-gel method, microwave method, microemulsion method, spray pyrolysis method, electrospinning technique and so on. In this paper, the progress of the above fabrication methods were summarized, and the advantages and disadvantages of these methods were discussed. Moreover, combining with our work on the fabrication of rare-earth-doped YAG nanomaterials, the development trends of preparation methods for rare-earth-doped YAG nanomaterials are also proposed.更多还原
