4,6-二乙酰基-2,5-二甲基间苯二酚铕配合物和协同配体(1,10-邻二氮杂菲、2,2’-联吡啶或2,2’-联吡啶N,N’-二氧化物)在二氧化硅基体中通过两步凝胶反应实现了原位合成.在二氧化硅凝胶中配合物的形成可以通过电致发光光谱来证明.含有原位合成的这种铕配合物的二氧化硅凝胶显示出有铕离子发射谱带特性.结果表明有两种方法可以加强铕离子(Ⅲ)的放射强度:(i)在二氧化硅基体中合成这种复合物;(ii)合成的铕配合物中应含有能有效转移能量到Eu(III)的协同配体. Diacetyl-2,5-dimethylresorcinol europium complex and a synergistic ligand (1,10-phenanthroline, 2,2’-bipyridyl or 2,2’- Bipyridine N, N’-dioxide) is synthesized in-situ by a two-step gel reaction in a silica matrix.The formation of a complex in a silica gel can be demonstrated by electroluminescence spectroscopy. The silica gel of this europium complex synthesized in situ showed the emission band characteristics of europium ion.The results showed that there are two ways to enhance the emission intensity of europium ion (Ⅲ): (i) In the silica matrix (Ii) the synthesized europium complex should contain a synergistic ligand capable of efficiently transferring energy to Eu (III).
