Abstract:

With the development of science and technology, more and more materials are coming out, at the same time,the demand for materials is increasing. Rare earth luminescent nanomaterials are different from conventional ones. They have the advantages of good physical and chemical stability, high temperature resistance, narrow luminescence band and high color purity which makes they show good prospect of applications in so many fields, such as light emitting devices, imaging and medicine and have become one of the hot spots. In this paper, the preparation and application of rare earth luminescent nanomaterials are reviewed, and the problems that need to be solved and the development prospects are discussed.

Key words: Rare earth, Nanomaterials, Preparation, Application

摘要： 随着科技的发展,越来越多的材料不断问世,同时,人们对材料的需求也在逐渐增加。稀土发光纳米材料不同于传统的发光材料,因其具有物理、化学性能稳定,耐高温,发光谱带窄,色彩纯度高等优点,在众多领域里显示出广阔的应用前景,如应用于发光器件、显像和医学等领域,已经成为材料研究领域的研究热点之一。综述了稀土发光纳米材料的制备以及应用,探讨了该类材料应用于实际亟待解决的问题以及发展前景。
