The complexes having the compositions of Eu(L1)(3)2H2O,Eu(L1)3phen,Eu(L2)(3)2H2O,Eu(L2)3phen (phen = 1,10-phenathroline,L1 = Dodecanoic acid, L2 = Stearic acid) were synthesized and characterized by elemental analysis and FTIR spectra. Their fluorescence spectra, UV spectra and TEM (Transmission Electron Microscope) have been investigated. The results show that the 5D0-7F1 and 5D0-7F2 transition of Eu(III) are observed in the emission spectrum of the particles at room temperature. As good photoluminescent materials, they may be useful in the regions of EL (Electroluminescence) or macromolecule composite materials doped with rare earth.
合成了组成为Eu(L1)₃·2H₂O、Eu(L1)₃phen、Eu(L2)₃·2H₂O、Eu(L2)₃phen（phen = 1,10 - 菲咯啉，L1 = 十二烷酸，L2 = 硬脂酸）的配合物，并通过元素分析和傅里叶变换红外光谱对其进行了表征。研究了它们的荧光光谱、紫外光谱和透射电子显微镜（TEM）。结果表明，在室温下颗粒的发射光谱中观察到了Eu(III)的⁵D₀→⁷F₁和⁵D₀→⁷F₂跃迁。作为良好的光致发光材料，它们可能在电致发光（EL）或掺杂稀土的高分子复合材料领域有用。
