稀土多酸膜的组装及其发光性质

多酸是一类具有拓扑结构的金属氧簇合物,在催化领域、生物学、电极、药物以及材料科学均有潜在应用,被称为无机高分子。多酸可以在某一格位接受电子,利用这一特性可以组装具有特定的光、电、磁学特性的膜材料;而稀土元素特殊的电子层结构,具有非常好的发光性能,LB膜可以在分子水平上控制膜的结构和膜厚度,因此研究稀土发光材料组装的LB膜对发光材料的理论研究和应用都具有非常重要的意义。本文总结了国内外近年来的研究结果。

Fabrication and Luminescence Properties of Rare Earth Polyoxometalate Film

Polyoxometalates(POMs) are a significant kind of inorganic metal-oxo cluster compounds and possess many potential applications in catalysis,conductivity,photo-and electrochromic devices,and molecular electronics,biology,medicine,and materials science etc.Because of receiving electrons at a crystal site of POMS,the film materials with definite optical,electronic,and magnetism properties materials can be fabricated.However,the excellent luminescence properties exists in the materials doped with rare earth elements.The film structures and thickness can be easily controlled at the molecular level by LB technology.It is extraordinary important for luminescence theory and application by studying the assembly LB film of rare earth luminescence materials.In present paper,the recent research results about the luminescence properties of rare earth POMS films have been reviewed in detail.
