摘　　要：稀土杂化材料在照明、发光、生物医药、光纤通信等领域中具有广泛的应用和发展前景,成为许多领域的研究热点。随着工业废物排放、沿海建设等一系列人类活动的进行,增加了海水中金属离子的浓度。本实验设计了一种独特的Eu^(3+)杂化材料,这种材料中含有昆布多糖、2-噻吩甲酰三氟丙酮(TTA)和邻菲罗啉(phen)三种配体,这三种配体对Eu^(3+)的发光有敏化作用。制备得到的Eu^(3+)-昆布多糖杂化材料融合了Eu^(3+)的发光特性和昆布多糖无毒、生物相容性等特征。这种新型杂化材料可附载到水下探测装置中,应用于海水中铁离子的监测。Rare earth hybrid materials have a wide range of applications and development prospects in the fields of lighting,luminescence,biomedicine,optical fiber communication,etc.,which become a research hotspot in many fields.With a series of human activities such as industrial waste discharge and coastal construction,the concentrations of metal ions in seawater have been increased.In this experiment,a unique Eu^(3+)hybrid material is designed,which contains three ligands,laminarin,2-thenoyltrifluoroacetone(TTA),and o-phenanthroline(phen),which have sensitizing effect on Eu^(3+)luminescence.The prepared Eu^(3+)-laminarin hybrid materials combine the good luminescence properties of Eu^(3+)and the non-toxic,biocompatibility characteristics of laminarin.This new hybrid material can be attached to underwater detection devices for monitoring Fe^(3+) in seawater.
