FTIR Spectra and Laser Excitated Spectra of Rare Earths Chlorate(Eu^(3+),Tb^(3+)) with Acetylalanine and Imidazole

用OPO激光为激发光源 ,对两种新型三元固态配合物氯化稀土 (Eu3+ ,Tb3+ )乙酰丙氨酸咪唑进行了荧光光谱测试 ,发现激光激发波长为 4 87nm时 ,铽配合物在 5 45nm处产生较强的铽(Ⅲ )离子特征绿色荧光谱线 ,激发波长为 4 6 5nm和 5 2 5nm时 ,铕配合物均在 6 13nm和 6 18nm处产生强的铕 (Ⅲ )离子特征红色荧光谱线 ;并且这两种稀土配合物的荧光均比相应稀土盐的强 分析了上述现象产生的原因 ,讨论了配体对中心离子发光性能的影响

Using the OPO laser as excitated lamp,the fluorescence spectra of the two new type ternary solid complexes of rare earths chlorate(Eu 3+,Tb 3+) with acetylalanine and imidazole have been studied.It has been observed that when the wavelength of the laser is 487 nm, the Tb(Ⅲ) complex produce relative strong characteristic green fluorescence of Tb 3+ at 545 nm,while the wavelength of the laser is 465 nm and 525 nm, the Eu(Ⅲ) complex produce strong characteristic red fluorescence of Eu 3+ both at 613 nm and 618 nm;and the fluorescence intensities of the two complexes are more stronger than its relevant rare earth salt. The cause of above phenomenon has been analysied.The effect of the ligand to the center ion′s spectral property has been discussed. At the same time, the FTIR and UV/VIS spectra of the title complexes have also been measured
