| 摘 要： | 在液相中合成了掺杂不同浓度Fe2 ,Fe3 的邻苯二甲酸铕系列配合物,测定了该系列配合物的荧光光谱和红外光谱.实验结果表明,微量Fe2 ,Fe3 的存在对邻苯二甲酸铕荧光产生了猝灭作用.这可能是由于配合物在发光过程中Fe2 捕获了基态的空穴或者Fe3 捕获了激发态的电子所引起的.

| Abstract: | A series of Eu-phthalate complexes doped with different concentration of Fe 2 ,and Fe 3 were synthesized in liquid phase,and studied by fluorescence spectra and FT-IR.The results show that Fe 2 ,and Fe 3 have quenching effect on the luminescence of Eu-phthalate complex possibly due to the capture of a hole in the ground state by Fe 2 ion or the capture of an electron in the excited state by Fe 3 ion during the irradiation. |
