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。
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.
