选择不同的条件,合成了 Tb~(3+)和 Eu~(3+)与均苯四酸、苯甲酸、吡啶-_3~2甲酸和喹啉哪酸等配合物。经元素分析和 X 射线晶体结构分析确定晶型为聚合网络状结构和链状结构。与 Eu~(3+)相比,Tb~(3+)配合物发光(Tb~(3+)~5D_4-~7F_(5.6))较强。配体对发光有影响,苯酸配合物发光呈较 Under different conditions, the complexes of Tb ~ (3+) and Eu ~ (3+) with pyromellitic acid, benzoic acid, pyridine-3 ~ 2carboxylic acid and quinolinecarboxylic acid were synthesized. By elemental analysis and X-ray crystal structure analysis to determine the crystal form for the network structure and chain structure. Compared with Eu ~ (3+), Tb ~ (3+) complexes are more luminescent (Tb ~ (3+) ~ 5D_4- ~ 7F_ (5.6)). Ligands affect the luminescence, benzoate complex was more luminous
