纳米技术近年来发展迅速,各种纳米材料在现代科学和技术中扮演着重要的角色。然而,单一功能的纳米材料其应用往往是比较有限的,为了赋予纳米粒子更加丰富与高效的功能应用,功能复合的纳米材料成为了一个重要的研究热点。稀土离子由于其特殊的光学及磁学性质而受到了广泛的研究。近年来研究表明,利用稀土离子对纳米材料进行功能化可以有效地提高稀土离子的稳定性,同时赋予纳米材料更加丰富的功能。这种复合纳米粒子从很大程度上扩展了传统纳米材料的应用范围,使其在生物成像、识别、检测、治疗等众多领域都有着重要的应用价值。本文综述了不同纳米材料与稀土离子复合的研究进展,探讨了各种稀土复合纳米材料的设计思路,为进一步研究多功能稀土复合纳米粒子提供了理论基础。 Nanotechnology has developed rapidly in recent years, and various nanomaterials play an important role in modern science and technology. However, the applications of single-function nanomaterials tend to be relatively limited. In order to give nanoparticles more abundant and efficient functional applications, functional nanocomposites have become an important research hotspot. Rare earth ions have been extensively studied due to their special optical and magnetic properties. In recent years, research shows that the use of rare earth ions to functionalize nanomaterials can effectively improve the stability of rare earth ions, while giving nanomaterials richer functions. This composite nanoparticle greatly expands the scope of application of traditional nanomaterials, making it an important application value in many fields such as biological imaging, identification, detection and treatment. This review summarizes the research progress of different nanometer materials and rare earth ions, and discusses the design ideas of various rare earth composite nanomaterials, which provides a theoretical basis for further research on multifunctional rare earth composite nanoparticles.
