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.
採用兩步溶膠-凝膠過程製備瞭含銪的三元配閤物的凝膠.熒光激髮光譜證實于SiO2基質中原位閤成瞭銪的配閤物.含銪配閤物的雜化材料髮齣銪的特徵熒光,與相應的純配閤物溶于乙醇相比,銪離子具有較長的熒光壽命.

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 Eu3+ and present longer fluorescence lifetimes than the corresponding complexes powder dissolved in ethanol solution.
