硝酸咪唑铕的OPO激光激发光谱

The OPO Laser Spectra of Europium Nitrate with Imidazole

对新合成的固体化合物硝酸咪唑铕以及对应稀土盐的OPO激光激发光谱进行了测试 ,观察到在 5 93nm处有较弱的荧光发射而在 6 16nm处有较强的荧光发射 ,并且稀土配合物的相对荧光强度比稀土盐的相应位置的荧光强度强 ,分析了配合物的这种光谱特性 ,讨论了配体对配合物光谱的影响

The OPO laser exicited spectra of the new synthesized solid compound and its related rare earth salt were measured. It has been observed that there is a relative weak fluorescence emission at 593nm while a relative strong fluorescence emission at 616nm,and the fluorescence intensities of the rare earth complex have increased as compared with those of the corresponding rare earth slat. The spectra property of the compound was analysised. The effect of the ligand to the spectra of compound was discussed.And the aqueous solution's UV/VIS spectra of the heading compound and its ligand were also measured.
