水热法制备微纳米荧光材料

摘要

无机材料的颗粒尺寸和微观形貌与它们的化学组成以及结构一样对其物理化学性质有重要的影响。在众多的材料合成方法中，水热合成因为在控制产物尺寸和形貌方面具有显著的优势逐渐得到了材料研究学者的广泛关注。荧光材料对分散性及均匀性有很高的要求，而各种类型的有机添加剂辅助的水热反应可以提高产物的均匀性、分散性，实现形貌的多样性。综述了水热合成制备微纳米结构荧光材料的现状，重点介绍了表面活性剂、生物大分子、有机酸、有机溶剂类等有机添加剂对水热合成过程的辅助作用并简单阐述了影响机理。最后，总结了目前在水热合成微纳米荧光材料领域存在的问题，并展望了其发展前景。%Generally,the physical and chemical properties of inorganic materials are strongly related to their chemical composition and microstructure,as well as particle size and morphologies.Among all synthetic meth-ods,the hydrothermal method has attracted more and more attention because of its outstanding advantages on controlling the size and morphology of materials.The dispersion and homogeneity are very important for the flu-orescent materials,and the organic additive-assisted hydrothermal syntheticstrategies may realize further con-trol of the morphology,uniformity and diversity of morphologies of the fluorescent material viathe introduction of various organic additives.In this paper,hydrothermal synthesis of micro-nanofluorescent materialassisted by surfactants,biological macromolecules,organic acids,organic solvent and other organic additives were reviewed and were briefly discussed.Finally,we conclude the problems existing in the hydrothermal synthesis and pres-ent the future prospects of this research area.
