无机纳米稀土发光材料的制备方法*

无机纳米稀土发光材料作为一种重要的发光材料，由于具有独特的光、电和化学性质，使其在高性能磁体、发光器件、显示、生物标记、光学成像和光学治疗等方面得到了广泛的应用。稀土发光材料的这些性质与材料的尺寸和形状密切相关，近年来研究者已经利用多种合成方法制备了不同形状的纳米稀土发光材料，包括纳米线、纳米棒、纳米管、纳米纤维和纳米片等。本文综述了无机纳米稀土发光材料的几种常用的制备方法，包括水热/溶剂热法、有机/无机前驱体热分解法和超声辅助合成法等，评述了这些方法的优缺点，并结合课题组在无机纳米稀土发光材料制备方面的工作，对无机纳米稀土发光材料制备方法的发展进行了展望。

Preparation Methods of Inorganic Nano Rare Earth Luminescent Materials

Inorganic nanosized rare earth luminescent materials as the important luminescent materials owing to their unique electronic, optical and chemical properties, have been widely exploited for use in high-performance magnets, luminescence devices, displays, biolabeling, optical imaging, phototherapy and so on. The intrinsic properties of rare earth luminescent materials depend strongly on the materials’ size and shape. Recently many methods have been used for the preparation of rare earth luminescent nanostructures with different shapes, such as nanowires, nanorods, nanotubes, nanofibers and nanoplates, etc. In this paper, a comprehensive review is presented on the general preparation methods of inorganic nano rare earth luminescent materials, including hydrothermal and solvothermal method, organic/inorganic precursers thermal decomposition method, sonication-assisted technique, etc. The advantage and disadvantage of these preparation methods is discussed. Moreover, combining with our work on the preparation of inorganic nano rare earth luminescent materials, the development trends of the preparation methods of inorganic nano rare earth luminescent materials are also proposed.
