摘　　要：0引言 镧系离子以其独特的光、电、磁、催化和分析等作用而受到人们的广泛关注,并进行了大量的研究。镧系离子本身发光效率低,目前,设计并合成含有稀土离子Tb^3＋和Eu^3＋的超分子配合物,作为发光分子器件和荧光探针成为稀土配位化学．材料科学，超分子化学，分析化学和生物化学等研究领域的热点课题之一。Two ternary solid complexes, Tb^3＋ （Eu^3＋）-ciprofloxacina-acetylacetone, have been synthesled and characterized by elemental analysis, IR. Ciprofloxacina is one kind of bacteriophage containing β-carbonyl carboxylic acid configurayion and acetylacetone contains β-diketonate configurayion. They are the ideal ligands for Tb^3＋ and Eu^3＋. The fluorescence spectra of Tb^3＋ and Eu^3＋ complexes showed that the ligands were suitable for efficient energy transfer from ligands to the Tb^3＋ or Eu^3＋ ion with a high fluorescence quantum yield, large stoke shift, narrow emission bonds and large fluorescence lifetime. So the complexes were the new kind of solid fluorescence materials. Moreover, the mechanisms of the fluorescence of Tb^3＋ （Eu^3＋）-ciprofloxacina-acetylacetone ternary solid complex were investigated.
