摘　　要：采用水热和回流2种方法合成了Cl-型层状稀土氢氧化物(Cl-LRH)(R为Y0.95Eu0.05),以此为前体,与去质子的4-联苯甲酸(加入NaOH)进行离子交换,合成了4-联苯甲酸根-YEu-LRH复合体.用XRD、FT-IR及PL等方法研究了其结构及性质,证明4-联苯甲酸根插入Cl-LRH层间,并发现其在层间有2种不同排列方式.与前体相比,所得复合体发光强度明显增强.The Cl-type layered rare earth hydroxide（Cl-LRH）（R=Y0.95Eu0.05） was synthesized by hydrothermal and reflux methods.Cl-LRH was used as precursor,NaOH was added to deprotonate 4-biphenylcarboxylic（BPC）,then BPC/YEu-LRH composite was synthesized by ion-exchange method.Products were characterized by XRD,FT-IR and PL.Data showed that BPC anion was intercalated into Cl-LRH,two different arrangements in the interlayers were found.In comparison with Cl-LRH precursor,the fluorescence intensity of composite increased significantly.
