摘　　要：以磷钼酸和烟酸为配体,采用水热合成法合成了一种新颖的含稀土钆的配合物,并对该配合物进行了元素分析、红外、紫外、荧光、电化学、热重等一系列表征。结果表明,该配合物在218 nm和261 nm处有两个很强的紫外吸收峰;在323 nm光的激发下,配合物在377 nm处有一个强的荧光发射峰;在-0.6~0.6 V(以饱和甘汞电极为参比电极)的电势范围内,配合物出现了两对氧化还原峰,电化学性能良好。同时该配合物具有较好的热稳定性。A novel rare earth gadolinium complex was synthesized with phosphomolybdic acid and nicotinic acid as ligands by hydrothermal method and characterized by a series of methods,such as elemental analysis,IR,UV,fluorescence,electrochemical analysis and thermal gravimetric analysis.The complex had two very strong UV absorption peaks at 218 nm and 261 nm and the complex had a strong emission peak at 377 nm under the excitation of 323 nm light.The complex had two pairs of redox peaks in the potential range of-0. 6 ~ 0. 6 V（a saturated calomel electrode was regarded as a reference electrode） which showed its good electrochemical activity.The thermal stability was good.
