稀土配合物 Eu(C4H6NO3)3(H2O)3的制备、表征及摩擦发光性质

摘要

以N-乙酰甘氨酸为配体,在无水乙醇中分别制备了La3+、Pr3+、Nd3+、Sm3+以及Eu3+五种稀土配合物.经元素分析和FTIR测定了配合物的组成.运用RAMAN光谱研究了具有摩擦发光性能的铕配合物的室温和低温的发光光谱.实验表明,在氩离子激光器照射下铕配合物发红光,最强发射峰为613 nm,表现为Eu3+的特征荧光.且该配合物摩擦时会发出与该稀土离子的荧光颜色相同的红色亮光.%The complexes of La + , Pr + , Nd + , Sm + and Eu + are prepared by using N-acetyl-glycine as ligand in ethanol, respectively. The components of the complexes are determined by elemental analysis and FTIR spectrum. The [Eu(C4H6NO3)3(H2O)3] , which has triboluminescence, is obtained firstly. It is investigated by spectrum of photoluminescence at room temperature and 77 K on SPX-1403. RAMAN. The europium complex emitted red light by irradiation in the argon ion laser. The peak maxima of [Eu(C4H6NO3)3(H2O)3] is observed at 613 run, which shows the characteristic fluorescence of Eu3 + . At the same time, the complex issues the same color of red light as that of fluorescent light by fracture or deformation of solids.
