报道了在水溶液体系中铕、铽与吲哚— 3—丙酸 (IP)形成固态二元配合物及铕、铽与IP、邻菲啉(phen)形成固态三元配合物。通过元素分析、红外光谱、紫外光谱、和热重—差热分析 ,确定了配合物的组成及成键特征。二元配合物组成为Ln(IP) 3 ·2H2 O ,三元配合物组成为Ln(IP) 3 ·phen ,其中Ln =Eu、Tb。在发光性能方面 ,三元配合物较二元配合物好
The solid binary complexes of europium, terbium with indole - 3 - propionic acid (IP) and europium, terbium with IP and phen were reported to form solid ternary complexes in aqueous solution. The composition and bonding characteristics of the complexes were confirmed by elemental analysis, IR, UV, TG-DTA. The binary complexes consist of Ln (IP) 3 · 2H 2 O and ternary complexes of Ln (IP) 3 · phen, where Ln = Eu, Tb. Ternary complexes are better than binary complexes in luminescent properties
