摘　　要：采用稀土铽氧化物 (Tb4 O7)、邻苯二甲酸氢钾 (KHPht)和邻菲啉 (Phen)合成铽三元配合物Tb(Pht) 3Phen ,通过机械共混、交联成型制备Tb(Pht) 3Phen/NBR或Tb(Pht) 3Phen/甲基乙烯基硅橡胶复合材料。扫描电子显微镜观察表明 ,机械混合后稀土配合物的粒径减小 ;荧光性能测试表明 ,当Tb(Pht) 3Phen质量分数达到一定值时 ,复合材料的荧光性能比Tb(Pht) 3Phen配合物好 ,且随着Tb(Pht) 3Phen含量增大 ,复合材料的荧光强度增大 ,直到Tb(Pht) 3Phen质量分数大于 0 .2 3 1时才出现“浓度猝灭”现象 ;Tb(Pht) 3Phen质量分数相同时 ,Tb(Pht) 3Phen /甲基乙烯基硅橡胶体系的荧光强度比Tb(Pht) 3Phen/NBR体系大。The ternary complexes of rare earth terbium were systhesized with terbium oxide(Tb_4O_7),potassium hydrogen phthalate(KHPht) and ortho-phenanthroline(Phen).The Tb(Pht)_3Phen/NBR or MVQ composites were prepared by mechanical blending and crosslinking.It was found by SEM that the particle sizes of complexes reduced by mechanical blending.The test results showed that the fluorescent property of composites,in which the content of Tb(Pht)_3Phen reached a certain level,were better than that of Tb(Pht)_3Phen complexes;the fluorescent intension of composites increased as the conten of Tb(Pht)_3Phen increased,and the “fluorescent quenching” wouldn’t appear until the content of Tb(Pht)_3Phen was greater than 23.1%;and the fluorescent intension of MVQ composite was greater than that of NBR composite.
