以2,4,6-三-（2-吡啶基）-1,3,5-三嗪（TPTZ）为原料，与TbCl3:GdCl3（0.1:0.9）在无水乙醇中室温反应制得配合物[Tb0.1Gd0.9(TPTZ)(H2O)(6)]Cl-3中心点3H(2)O。单晶x射线衍射表明，金属原子与来自一个TPTZ配体的3个氮原子和来自6个水分子的6个氧原子9配位。这种复合物在紫外光下发出强烈的绿色荧光。发光峰对应于Tb3+离子的特征发射D-5(4)-> F-7(J) （J = 3-6）跃迁。
The complex [Tb0.1Gd0.9(TPTZ)(H2O)(6)]Cl-3 center dot 3H(2)O was prepared through the reaction of 2,4,6-tris-(2-pyridyl)-1,3,5-triazine (TPTZ) with TbCl3:GdCl3 (0.1:0.9) in absolute ethanol at room temperature. Single crystal X-ray diffraction revealed that the metal atom is nine-coordinated with three nitrogen atoms from one TPTZ ligand and six oxygen atoms from six water molecules. The complex emits intense green fluorescence under ultraviolet light. The luminescence peaks correspond to the characteristic emission D-5(4)-> F-7(J) (J = 3-6) transitions of the Tb3+ ion.
