The complex of Eu(Ⅲ) with 1-(6-hydroxy-1-naphthyl)-1,3-butanedione (HNBD) was prepared for the first time and characterized by elemental analysis, IR, UV, fluorescence spectrum, and DTA-TG-DTG techniques. The IR and UV-visible spectra showed that Eu(Ⅲ) ion was coordinated to the HNBD ligand. The fluorescence spectrum showed the presence of Eu3+ characteristic emission. The TG-DTA-DTG curves showed that the thermal decomposition of the anhydrous complex was a two-stage process and the final residue was Eu2O3. The thermal decomposition kinetic ...

有 1-(6-hydroxy-1-naphthyl ) 的 Eu (III ) 的建筑群 -1,3-butanedione (HNBD ) 第一次被准备并且由元素的分析描绘了，红外，紫外，荧光光谱，和 DTA-TG-DTG 技术。红外和紫外可见的系列证明那个 Eu (III ) 离子被协调到 HNBD 配位体。荧光光谱显示出 Eu (3+) 的存在典型排放。TG-DTA-DTG 曲线证明无水的建筑群的热分解是一个二阶段的过程，最后的残余是 Eu2O3。热分解建筑群的运动参数被使用三种不可分的方法从 TG-DTG 数据评估(Coat-Redfern 方程， Horowitz 和 Metzger 方程， Madhusudanan-Krishnan-Ninan 方程) 。第一个阶段的运动参数是 E (*)= 164.02 kJ ·m ol (? 1 )，= 1.31 × 10...
