【摘要】 在乙醇-水溶液中,水浴60℃合成了一系列不同配比的稀土掺杂（Nd/Dy）-L-谷氨酸（L-Glu）-邻菲啰啉（Phen）三元固体配合物。利用元素分析、摩尔电导、紫外光谱、红外光谱、热重差热分析等表征,推测出配合物组成为[Nd_xDy_1-x（L-Glu）₃Phen]Cl₃·nH₂O。通过荧光光谱对配合物的发光特性进行了探讨,当Nd和Dy掺杂比达到1∶3时,配合物荧光强度最大。最后通过循环伏安法对配合物的电化学活性进行了研究,设定扫描电位-0.30^-0.80V（vs.SCE）,五种配合物在HAc-NaAc缓冲溶液（pH约6.0左右）中均表现出电化学活性,电化学活性中心是RE3+,电化学行为是准可逆的,配合物还原峰电流与扫描速度及浓度呈现出递增关系。更多还原

【Abstract】 In the ethanol-water medium,a series of doped ternary complexes of Nd / Dy-L-glutamic acid-1,10-phenanthroline was synthesized in different proportion of Nd / Dy. Through molar conductance,complexometric titration analysis,elemental analysis,infrared spectra（ IR） and TG-DTG analysis test,the general formula of the complexes were conformed to [Nd_xDy_{1- x}（ L-Glu）₃Phen]Cl₃·nH₂O. Then fluorescence spectra were used to discuss their glowing characteristics,and when Nd³⁺ and Dy³⁺doping ratio was set as 1 ∶ 3,the fluorescence intensity achieved maximum. Finally electrochemical behavior at a platinum working electrode was tested by cyclic voltammetry. The complexes showed the electrochemical activity at- 0. 30 ^- 0. 80 V（ vs. SCE） in the HAc-Na Ac buffer solution（ pH≈6. 0）. The RE³⁺ was electrochemical active center in rare earth complex. The results showed that the complex was a quasi-reversible system and it showed the increasing relationship between the coordination compound’s reduction peak and concentration.更多还原
