| 摘 要： | 采用两步溶胶－凝胶过程制备了含铕的三元配合物的凝胶。荧光激发光谱证实于ＳｉＯ２基质中原位合成了铕的配合物。含铕配合物的杂化材料发出铕的特征荧光，与相应的纯配合物溶于乙醇相比，铕离子具有较长的荧光寿命。

| Abstract: | The gels containing ternary
europium complexes have been prepared by a two-step sol-gel method.Europium complexes
are in-situ synthesized in sol-gel derived silica/poly(hydroxyethyl methacrylate) matrix,and
confirmed by the luminescence excitation spectrum.The hybrid materials that contain europium
complexes exhibit the characteristic emission bands of Eu 3 and present longer
fluorescence lifetimes than the corresponding complexes powder dissolved in ethanol solution. |
