众所周知,稀土元素是包括周期表中的镧系元素(z=57～71)和钪、钇等十七个元素,稀土元素的电子层结构和核结构决定了稀土元素及其化合物的性质,而稀土元素的许多独特性质又决定了它们的应用。因此对稀土元素化合物的性质及结构进行研究,探索稀土金属在新材料方面新的应用是有意义的。本文报道了二碘荧光素、四碘荧光素及其稀土配合物的半导体导电性质及结构,这些工作尚未见文献报道。
As we all know, the rare earth elements are periodic elements of the lanthanide (z = 57 ~ 71) and scandium, yttrium and other seventeen elements, rare earth elements of the electron layer structure and nuclear structure determines the properties of rare earth elements and their compounds, and Many unique properties of rare earth elements in turn determine their application. Therefore, it is significant to study the properties and structure of rare earth compounds and to explore new applications of rare earth metals in new materials. In this paper, the semiconducting properties and structures of diiodofluorescein, tetraiodofluorescein and their rare earth complexes have been reported. These studies have not been reported in the literature.
