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^3＋,Pr^3＋,Nd^3＋,Sm^3＋ and Eu^3＋ 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 nm,which shows the characteristic fluorescence of Eu^3＋.At the same time,the complex issues the same color of red light as that of fluorescent light by fracture or deformation of solids.
