【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。更多还原

【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.更多还原
