| 摘 要： | 合成了一系列异核配合物(Eu1-xPrx)(DPSO)(phen)3(ClO4)2]ClO4*nH2O(x=0.000～0.200, DPSO为二苯亚砜, phen为邻菲罗啉, n=1, 2, 3, 4, 5, 6). 对配合物进行了组成分析, 摩尔电导, IR光谱及荧光激发和发射光谱的测定. 荧光光谱测定结果表明 本身不发光的Pr3+对Eu3+的发光产生较大影响, 当Pr3+的掺入量为0.001 mol时, 可使Eu3+的发光强度提高到200%以上,随着Pr3+浓度的增大,对Eu3+的发光先敏化后猝灭.Eu3+在配合物中所处的格位对称性低,无对称中心.

| Abstract: | Different nuclear (Eu(1 - x)Pr(x))(DPSO)(phen)3(ClO4)2]ClO4 x nH2O (x = 0.000-0.200, DPSO as the abbreviation for diphenyl sulfoxide and phen for 1,10-phenanthroline, n = 1-6) coordination compounds were synthesized, and were studied by means of composition analysis, conductance, IR spectra and fluorescence excitation and emission spectra. In the fluorescence spectra it was found that Pr3+ has a great influence on the luminescence of Eu3+. The fluorescence emission intensity of europium perchlorate was enhanced when doped with 0.001-->0.100 mol Pr3+. The local symmetry of Eu3+ site is low in this coordination compounds. |
